Is Self-Improvement Selfish?

You’ve decided to make a change:
- Training for a triathlon instead of watching TV with your spouse.
- Reading a book a month. Or a book a week.
- Waking up at 5:00 AM to write your novel while your kids sleep.
Good on ya! You’re making a conscious effort to get better at life.
But how noble are you, really?
I mean, this personal development stuff is kinda all about us, right?
