It's a fair point, and I can't really know how much of it was just me maturing as a person.

I can say, though, that making these changes at any point in my life would have been a vast improvement. Sleep and nutrition help me view life in a much better lens and exercise gives me a structured, constructive outlet and scheduled time for reflection.

That’s one of those things that enables a lot of empathy I find - given the people I was around and what my life was like before my 20s, I certainly found it near impossible to actually make healthier life choices. Wanting to make the choices doesn’t matter as much as having the skill set and self knowledge to put yourself in a position to do them - powering through as a rule for me just leads to burnout, and ends up being incredibly unkind to myself which leads to worse habits.
