From a good article I clipped by Mens' Health writer, Mike Zimmerman:
Choosing to Marry
- Will you want to be with her in 20 years?
Becoming a Father
-Kids' needs first, otherwise you suck at being a dad.
Receiving Your First Real Defeat
- Not losing a game, the adult defeats: loss of employment, divorces, estrangements cut deeply into the ego.
Becoming an Orphan
- No more training, no more adivce. It's your turn to be the example.
Realizing You Don't Know Everything
- The younger you are when you figure this out, the better.
