As they say in the bible, that you're supposed to rejoice when people die and mourn when they're born, because it's one of the most painful acts you go through in life, is being born, and dying.
Perfection is immutable. But for things imperfect, change is the way to perfect them.
I think this happens to a lot of people, men and women, where you reach a point in your life and all of a sudden realize that things have changed. You suddenly realize that people are coming up behind you, that maybe somebody might want to replace you for less money.
