If not for anything else, build your life now.
Build relationships.
Build skills.
Build something that can sustain you.
Build a community around you.
Because one of the hardest things about old age isn't getting older.
It's getting older and realizing you have nobody to call, nothing meaningful to do, and no capacity to change it.
Work hard while you still have the strength.
Not just to become wealthy.
But to give your future self options.
