Before you are old, attend as many funerals as you can bear, and listen. Nobody talks about the departed’s achievements. The only thing people will remember is what kind of person you were while you were achieving.
The future isn't written in the stars. There are no guarantees. So claim your adulthood. Be intentional. Get to work. Pick your family. Do the math. Make your own certainty. Don't be defined by what you didn't know or didn't do.
