OP is not wrong. Time is running out. His best physical years are behind him. On the plus side he has deep experience. He probably has seen quite a bit. Maybe his feeling of having seen everything is justified.
Existential dread is a bit of a thing, but it comes for the successful and the truly unsuccessful alike.
OP is also probably right, it's probably time to find a new passion, in tech or outside of tech. All of the other advice in this thread to really make sure you're focused on your health in all forms from this age forward is spot on.
They could be. Or it could depend on OP. Tom Brady has more Super Bowl Trophies and MVP selections from __after__ he was 37.
There are plenty of athletic sports where being young does not offer easy superiority.
I didn't mean anything beyond pure athleticism. Sport is another matter.
Physically, it's much more tricky to train and become an at an older age. But I'll agree that for some folks, you can be a better version of yourself at earlier ages -- it is just dependent on what type of athlete you were then, and much permanent damage your body has sustained over the years.
I ran sub 17 5k at 18 years old. Will my tendons and knees support the kind of workload that is required to attempt that again?
One day, your body will fail. Even Tom Brady knows father time always, always wins. You have to choose your battles and figure out where you want to spend your time.
I don't see the bragging part, personally.
