Advice to My 40 Year Old Self
I think of 40 as a preparation decade.
By then, you’ve been educated — formally or by life. You’ve had success. You’ve had humiliation. You know roughly who you are. But in your 40s, theory ends and consequence begins.
Every plate spins at once: career, children, partnership, aging parents, long-term money, health, relevance. It’s no longer about potential. It’s about management.
Forty is convergence.
This is the decade where discipline stops being aesthetic and becomes strategic. It’s not about being admired. It’s about being structurally sound.
When I turned 40, I already understood the stakes. Two difficult pregnancies had stripped away any illusion of invincibility. My life had never mattered more to me than when I was given the gift of children. Our survival was intertwined. If I went down, everything shifted.
That realization clarifies you.
So my 40s weren’t about proving. They were about protecting.
Health is power.
Power requires health.
You cannot separate them. Financial instability creates chronic physical stress. Chronic stress erodes the body. Poor health destabilizes income. The loop is real. And your 40s are when you decide whether that loop strengthens you or weakens you.
If you drift through this decade, you pay for it in your 50s.
You pay in bone density.
You pay in metabolic resilience.
You pay in savings you didn’t build.
You pay in relationships you didn’t maintain.
You pay in options you assumed would always be there.
And then something else happens in your 40s: you begin to lose people your own age. Sometimes to illness. Sometimes to despair. Sometimes to a twist of fate that reminds you how fragile all of this is.
Mortality stops being abstract.
That’s when the work deepens beyond productivity and aesthetics. Yes, lift heavy weights. Yes, challenge your brain. But those are tactics. The strategy is larger:
Who are you when output slows?
What sustains you when ambition quiets?
Have you built a life that protects you as fiercely as you protected everyone else?
Forty is halftime. And halftime is assessment.
Life is good. But it is not casual.
You have to treat yourself well to live life well.
Build systems. Build savings. Build bone density. Build friendships that will answer the phone at 3 AM.
