Measure your life in decades.
Do your future self favors. Don’t spend, lock it up.
Keep building and growing, be ambitious, yet recognize there is a cycle and you will burn out.
You will be at your prime when you are 35 (if you take proper care of yourself.) you will be old some time after 50, and probably dead (or not much better off) by 100.
The problem most have (unaware to themselves) is not that they don’t live long enough, it is that they are a waste of what life they have.
