Yes, I created a few. One is that I say:
“Everyday, in every way, I am getting thinner, stronger, and smarter”
(even if it ain’t true- its good to hear)
“Things are going to work out just fine” (Used approx. 101 times a day lately!)
“I have the power within me to control my life in the direction I want to go in”. (this one actually helped instigate my initial return to Judaism!)
My personal favorite, which ironically I hardly use is:
“Before I diagnosis myself as angry, bi-polar, BOrderline personality or anxiety disorder, first do a check if I am not in fact surrounded by jerks”
