😟 27 Lessons About Stress and Worry
Filed under: Leadership & Managing People, Learning & Growth
The responses to one of my last newsletter were overwhelming.
Project managers, superintendents, and executives from across the industry told me the relationship principles from Carnegie's "How to Win Friends and Influence People" immediately improved their leadership effectiveness within days.
(Read it here: How To Become The Person Everyone Wants to Work With)
But here's what dozens of you told me: "This helps with people, but what about the crushing stress that's killing my performance?"
Stress is a funny thing.
It consumes an enormous amount of our mental energy and decision-making capacity in leadership roles, but very few of us learn anything about managing it effectively.
If we're lucky, we pick up a few stress management tips from mentors or leadership courses along the way. But we're pretty much left on our own when it comes to one of the most influential elements in our professional performance.
I'm in my second decade of leading complex projects and I've spent a lot of time thinking about stress management over the last few years. I've had conversations with hundreds of project leaders across every industry, from those barely hanging on to executives running billion-dollar programs with supernatural calm.
The construction industry has the highest stress levels of any profession, but it doesn't have to define your performance or destroy your health.
Today, I'd like to share what I've learned...
27 lessons about stress and worry from Dale Carnegie's "How to Stop Worrying and Start Living":
Part 1 - Fundamental Principles for Overcoming Worry
1. Live in "day-tight compartments."
Your mind can only control what's directly in front of you right now.
When you focus exclusively on today's challenges and opportunities, you eliminate the mental energy drain of replaying yesterday's mistakes and rehearsing tomorrow's disasters.
I know a superintendent who was losing sleep over a three-month delayed project that was out of his control until he started asking: "What can I accomplish in the next 8 hours?" His stress levels dropped immediately and his problem-solving improved.
Action builds momentum while worry kills it.
2. Face trouble systematically:
Ask yourself, What is the worst that can possibly happen?
Prepare to accept the worst.
Try to improve on the worst.
Vague anxiety is like fighting shadows.
When your key vendor calls with potential delays, don't spiral into catastrophic thinking. Write down exactly what you're worried about: "The client rejects our revised timeline and we have to bring in additional crews at premium rates."
Once you've identified the specific worst case, mentally accept it as a possibility, then channel your energy into making it less likely or less damaging.
This transforms overwhelming dread into concrete problems you can actually solve.
3. Remind yourself of the price you pay for worry in terms of your health and performance.
Chronic worry triggers the same stress response as physical danger.
It floods your body with cortisol, weakens your immune system, and impairs the judgment you need for complex decisions. A study of Fortune 500 executives found that those with chronic anxiety made 23% more strategic errors than their calmer counterparts.
When you prioritize mental health, you're not being soft. You're protecting your most valuable leadership asset: clear thinking under pressure.
Part 2 - Basic Techniques in Analyzing Worry
4. Get all the facts.
Half of all project stress comes from making decisions with incomplete information.
When my subcontractor called saying they might be delayed, I immediately started panicking about schedule impacts until I gathered actual facts: the delay was only 2 days and we had buffer in that work stream. I'd wasted hours of mental energy on a non-problem because I'd made assumptions instead of gathering data.
Facts replace fear and enable reality-based decisions instead of anxiety-driven reactions.
5. Once a decision is reached, act!
Hesitation after decision-making breeds second-guessing and anxiety.
Once you've decided to bring in additional resources, don't spend the next week questioning whether you chose the right approach. Focus on making your solution work effectively.
You build confidence through committed action, not through endless revision.
6. Problem solve by writing out and answering these five questions:
What is the problem?
What are the causes of the problem?
What are the possible solutions?
What is the best possible solution?
What evidence supports this choice?
This framework forces you to move from emotional reaction to logical analysis.
I was once stressed about "team conflicts" until this process revealed the real problem was unclear role definitions, making the solution obvious: implement a responsibility matrix.
Most problems seem overwhelming because we haven't defined them clearly. Writing forces clarity.
Part 3 - Break the Worry Habit Before it Breaks You
7. Keep busy with meaningful work.
An idle mind is worry's playground.
When you're actively engaged in productive tasks, there's no mental space for anxiety. During project delays beyond your control, focus on planning the next phase, improving processes, or developing your team instead of ruminating on what's not moving.
I've never met a project leader who worried excessively while actively solving problems.
8. Don't waste energy on trivial matters.
Ask yourself: "Will this matter in 5 years? 5 months? 5 days?"
Most daily anxieties fail this test completely. Don't lose sleep over someone being 15 minutes late to a meeting or minor formatting errors in status reports.
Your mental energy is finite and valuable. Focus on strategic milestones, budget variances, and team performance issues that actually impact project success.
9. Use the law of averages to outlaw your worries.
Examine the actual probability of your fears occurring instead of treating every concern as inevitable.
If you're worried about catastrophic equipment failure, research actual failure rates for similar projects. You'll often discover your anxiety is disproportionate to real risk.
Facts replace inflated fears and enable rational risk management decisions.
10. Cooperate with the inevitable.
Some things cannot be changed: weather delays, design changes, regulatory requirements, market fluctuations.
When new safety regulations require process changes, don't waste energy complaining about bureaucracy. Use it to implement efficient compliance systems that might actually improve operations.
Fighting unchangeable realities drains energy you need for areas where you can make a difference. Save your ammunition for battles you can win.
11. Decide just how much anxiety a thing may be worth and refuse to give it more.
Not every problem deserves the same level of mental energy.
A minor subcontractor delay doesn't warrant the same stress response as a major safety incident. Before reacting emotionally, ask: "Is this a $1,000 problem or a $100,000 problem?"
Match your mental investment to the actual impact. Most things aren't worth losing sleep over.
12. Don't worry about the past.
The past is fixed and no amount of worry will change what happened.
If a major mistake occurred last month, extract the lessons and implement better processes going forward instead of endlessly replaying what went wrong. You make progress by building solutions, not by dwelling on unchangeable problems.
The only thing worse than making a mistake is making it twice.
Part 4 - Cultivate a Mental Attitude That Will Bring You Peace and Happiness
13. Fill your mind with though of peace, courage, health, and hope.
Your mind can only hold one thought at a time effectively.
When you consciously focus on positive possibilities, there's no room for anxiety to take root. Instead of visualizing everything that could go wrong with tomorrow's client presentation, visualize successful outcomes and the specific steps that will create them.
This isn't wishful thinking. It's mental preparation that often becomes self-fulfilling prophecy through improved confidence and performance.
14. Never try to get even with your enemies.
Holding grudges against difficult clients, competitors, or team members gives them free rent in your head while accomplishing nothing productive.
I once witnessed a co-worker who stopped plotting against a backstabbing colleague found his stress levels dropped dramatically and his performance improved.
Energy spent on resentment is energy not spent on excellence. The best revenge is massive success.
15. Expect ingratitude and you'll never be disappointed.
Don't let unmet expectations for recognition become a source of ongoing stress.
Most people are consumed with their own problems and rarely express gratitude even when they feel it. When you expect nothing and receive appreciation, it's a pleasant surprise rather than a crushing disappointment.
You maintain motivation through professional pride rather than dependency on others' approval.
16. Count your blessings, not your troubles.
Worry has a spotlight effect that makes problems seem larger and more numerous than they actually are.
At day's end, identify three things that went well: a milestone reached ahead of schedule, a team member who exceeded expectations, a potential issue caught early.
This isn't toxic positivity. It's accurate accounting that prevents negative bias from distorting your perception of reality.
17. Stop comparing yourself to others.
Comparison is anxiety's best friend because other people's highlight reels make your behind-the-scenes struggles seem worse than they are.
Focus on your progress against your own goals rather than comparing yourself to other leaders' apparent successes.
You reduce unnecessary stress by competing with your own standards rather than others' perceived achievements.
18. Try to profit from your losses.
Every mistake contains lessons that can prevent future problems or create new opportunities.
A project that went 20% over budget taught one leader to implement cost tracking systems that saved hundreds of thousands on subsequent projects.
When you automatically ask "What can I learn from this?" instead of "Why did this happen to me?", setbacks become investments in future performance.
19. Create happiness for others.
When you focus on making others' lives better, you naturally worry less about your own problems.
Mentor a junior project manager, help a colleague solve a technical challenge, or recognize someone's exceptional work publicly.
Making others successful makes you feel successful while building the relationships that make your job easier. Generosity is anxiety's antidote.
Part 5 - Don't Worry About Criticism
20. Remember that unjust criticism is often a disguised compliment.
People rarely criticize those they consider insignificant.
Unjust criticism often means you're doing something important enough to threaten someone's position or ego. When a competitor criticizes your approach, consider that it might reflect their concern about your success rather than legitimate flaws in your methods.
You maintain confidence despite criticism by understanding its true source and motivation.
21. Do the very best you can, then let the chips fall.
When you know you've given your absolute best effort with available resources and information, external criticism loses its sting.
A project manager who thoroughly prepared for a challenging presentation felt confident even when stakeholders questioned his recommendations because he knew he'd done everything possible.
You develop unshakeable confidence by meeting your own standards of excellence rather than trying to please everyone.
22. Analyze your own mistakes and criticize yourself.
When you honestly assess your own performance, you remove others' power to shake your confidence.
After every major outcome, identify what you could have communicated more clearly or prepared better, then address these issues proactively.
Self-awareness becomes a shield against external criticism while maintaining control over your development narrative. Beat them to the punch.
Part 6 - Prevent Fatigue and Worry, and Keep Your Energy and Spirits High
23. Rest before you get tied.
Your body and mind perform best when you prevent exhaustion rather than recover from it.
Schedule regular breaks throughout your day and take them regardless of workload pressure. A superintendent who started taking 10-minute breaks every two hours found his decision-making quality improved dramatically during long days.
You maintain peak performance longer by preserving energy instead of constantly depleting and recovering it.
24. Learn to relax at your work.
Tension and stress are often habits rather than necessary responses to challenging situations.
Practice deliberate relaxation techniques during your workday: deep breathing when reviewing budget reports, progressive muscle relaxation during site walks, brief meditation before difficult conversations.
Physical relaxation enables mental clarity. You can't think clearly when your body is wound tight.
25. Apply these four good working habits:
Clear your desk of all papers except those relating to the immediate problem at hand.
Do things in the order of their importance.
When you face a problem, solve it then and there if you have the facts necessary to make a decision.
Learn to organize, deputize and supervise.
Once I implemented these habits, I found stress levels dropped dramatically while my productivity soared. Mental energy is finite. Preserve it for important decisions by systematizing routine choices.
Good systems eliminate decision fatigue.
26. Put enthusiasm into your work.
Enthusiasm is contagious and creates positive momentum for you and your team.
Even routine tasks become engaging when you consciously connect them to larger goals you care about. This isn't fake positivity about genuinely difficult situations. It's finding authentic meaning in your daily work that energizes rather than drains you.
Energy attracts opportunity.
27. Don't worry about insomnia.
Worrying about not sleeping creates a vicious cycle that makes insomnia worse.
When you can't sleep, use the time for light reading, planning, or relaxation instead of stressing about being tired tomorrow. Sleep researchers found that fear of tiredness often causes more problems than actual fatigue.
You break the worry-insomnia cycle by accepting sleeplessness rather than battling it.
The Bottom Line
Your projects need a leader, not a worrier.
Your team needs confidence, not anxiety.
Your family needs you present, not paralyzed by what-ifs.
When your mind is consumed with anxiety about what might go wrong, you can't focus on making things go right. When you're paralyzed by fear of failure, you can't take the bold action that success requires.
Leadership stress is just poorly managed mental energy. When you master worry before it masters you, everything else becomes easier.
The challenges won't disappear, but you'll handle them with the clarity and confidence that separates exceptional leaders from everyone else.
After all, 90% of what we worry about never happens anyway.
