Honestly, I think superpowers would be wasted on most people. If you woke up tomorrow, say, with the ability to shapeshift into an alternate, more powerful form, Likeliness is you'd be freaked out. That rules out any instant heroics, more or less...and most people would spend the rest of their life trying to be as "normal" as possible. Certainly, even among people who embrace said form, very few would actually aim to attract attention.
I would, however, probably completely waste telekinesis. I'd probably also do even less physical activity than I currently do.
