Power? Like superpower?

Ok. So I've been doing JustDance more lately. It's my favorite workout. I like it because I work up a sweat, and if I'm doing good I get "perfect" "good" or "ok." It's encouraging. And on JustDance 4, I do JustSweat: Cheerleader's Bootcamp. It's amazing! You pick how long you want to do it for and go at it! It's great because it pushes you. When I finish a workout, I feel powerful! What's your source of power? Is it a tough workout? A song? Maybe it's doing the right thing when no one else is? Comment below! Anyway, having something that makes you feel powerful is important because if you let the feeling continue, you are bound to accomplish something. What is your source of power?
