43 Lessons in 43 Years!

Turning 43 feels different.

Not celebratory in a loud way. Not sad. Not heavy - but honest.

It feels like standing in the middle of a life that has been full, stretched, broken open, rebuilt and refined - and finally having the words for what I wish I had known sooner.

I’m a working mom of four.
I’ve navigated postpartum darkness, anxiety, burnout, advocacy, health struggles, business building, seasons of isolation and seasons of deep connection.

And if there’s one thing I know for sure at 43, it’s this:
You don’t arrive at wisdom - you earn it by living.

So here are 43 lessons I’m carrying with me into this next year. Not as rules. Just as truth…|

  1. You don’t “find yourself” - you build yourself, one hard season at a time.

  2. Peace is more valuable than productivity, even when the world rewards the opposite.

  3. Some years aren’t for growth - they’re for survival and simply showing up still counts.

  4. You are allowed to outgrow versions of yourself that once kept you safe.

  5. The older I get, the smaller my circle gets and the fuller my life feels.

  6. You don’t need permission to change your mind or your pace.

  7. Protecting your energy is not selfish - it’s self-leadership.

  8. You don’t have to explain why something feels heavy to you.

  9. My body was never the enemy, I just wasn’t listening enough to what it needed.

  10. Fatigue is feedback, not failure.

  11. Weight resistance taught me more about stress and hormones than willpower ever could.

  12. You cannot out-discipline a dysregulated nervous system.

  13. Hormonal shifts don’t ask for your permission - hey demand your awareness.

  14. Health got easier when I stopped doing more of what I was “supposed to do” and started doing what actually felt good and worked for me.

  15. Consistency, not intensity, is what’s changing my body and my energy.

  16. Stress management is health care. This cannot be skipped!

  17. Feeling good is something you have to work for.

  18. Anxiety isn’t a weakness - it’s the body raising the white flag, asking for support.

  19. Therapy didn’t “fix” me; it keeps helping me understand myself.

  20. You’re allowed to need help even if others think you “handle things well.”

  21. Emotional regulation is a skill and it’s a muscle to workout every damn day.

  22. Healing is quiet, non-linear and often invisible to everyone but you.

  23. Being sensitive and wearing your heart on your sleeve is not a bad thing.

  24. Peace and the mundane feel boring only when chaos has been normalized.

  25. Self-care isn’t bubble baths - it’s BOUNDARIES.

  26. Saying no is often the most loving thing you can do for yourself and others.

  27. You don’t need perfect routines - you need supportive ones that work WITH your needs.

  28. Taking care of myself taught my kids more than any lecture ever could.

  29. Slowing down doesn’t make me less ambitious - it makes everything feel more sustainable.

  30. You don’t owe anyone an explanation for prioritizing your health. Or your goals. Period.

  31. Not every friendship is meant to last forever - and that’s okay.

  32. Depth, reciprocated energy matters more than anything else.

  33. The right people don’t make you feel guilty for evolving.

  34. Being understood matters more than being liked.

  35. Protect your energy like you protect your kids.

  36. Being a mom of four taught me I can do hard things - even when I don’t think I can.

  37. You don’t need to be a perfect mom to raise good humans.

  38. Advocacy often begins with your own story - even when it’s uncomfortable to tell.

  39. Using your voice gets easier once you stop trying to please someone else.

  40. You can be deeply grateful for your life and deeply tired by it - both can coexist.

  41. Success without alignment is burnout in disguise.

  42. You were never meant to shrink to make others comfortable.

  43. The woman you’re becoming deserves your fire, your passion, your grit! Go create her!


I don’t feel like I have everything figured out. Because I never will…

But as 43 comes around - I do feel clearer. More grounded. Less interested in proving anything.
Or forcing or chasing my way into a better version of myself. But rather - focusing most on supporting my needs (from the inside out) every step of the way - as I build into the woman I’m meant to be.

If you’re in a similar season - tired, wiser, softer, stronger - I hope this reminds you:

You’re not behind.
You’re not broken.
With every passing year…
You’re becoming.

And that is more than enough.
