What do you think of first when you think of "Power?" It's probably pretty messed up. We think of kings, politicians, abuse thereof. Maybe we think of athletes, celebrities or personal heroes. But in terms of yourself, what's inside you, how do you work with and visualize that? The basic definition of power is " the ability to do or act; capability of doing or accomplishing something." 

This is very similar to how we use the word "potential" in physics, to describe stored energy, energy that can (and very likely will) be used.
