I struggled a lot with purpose until my first son was born. Then life suddenly snapped into perfect clarity. I also had this instant revelation about what "faith" really means to the religious. It was a beautiful feeling to know, without any doubt or waivering confidence what your purpose is. It makes every decision I ever have to make really simple, because it always boils down to what is best for my kids.

Am I "happy"? I dunno. My 10 month old woke me up 5 times last night and as a result today was a stunningly miserable slog. But I have meaning, and that gives me direction and tremendous joy.
