I realized around 35-36 (only a few years ago) that the doors are actually closing, especially on physical activity related goals and travel... both as far as health/potential is concerned, and as far as time is concerned. I feel like I wasted quite a bit of time in my late 20ies-30ies. Even when doing something (e.g. outdoor stuff) I wish I was more focused on training, or traveling to exciting places, etc., and spent less time just dicking around with the hobby and doing whatever. Same applies to other pursuits like personal projects, although to a lesser extent because brain don't degrade as far as muscles. And probably work, although it's too early to tell. I wish I realized it earlier :)
