Power
You love being a PT, and you fervently wish you had the power to part seas, order manna to rain down from heaven (along with the pennies), and completely cure your hurting, infirm patients. But you know you can't always get what you want, and you're okay with having the power to inspire, cheer on, encourage, and motivate your charges to help heal themselves. You learned in your years of training how powerful PT methods can be.
Sometimes, however, your patients get in the way of your exercising this awesome power. They resist, they pout, they cry, they die.
That can put a dent in your PT-as-God complex.
