Going along with Wakeup, what you should do whether you believe it or not is start telling yourself how worthy you are, what an awesome smart person, you rock, etc...........
I used to do that to myself as well and decided I was going to tell myself in the mirror everyday how AWESOME I was and what a "kick @ss" person I am. It didn't take long before I believed it and followed suit.
Absolutely with Bam, you don't need to kick yourself, BE YOUR BIGGEST CHEERLEADER!!!!!
