Don't compare. Just don't. It only hurts you.
Say yes more.
But also learn when to say no and don't be afraid to do it.

Pray! And constantly. After all, He is the only one that is really in control, so why not give Him all the worry, angst, sadness and pain?
Pay your bills on time (unless you absolutely cannot- and then a late fee is better than not at all).
Wear more lipstick- it will make you feel more confident.
Only wear heels if you know you'll be off your feet a majority of the time.
