Who Shall Wield the Power?
It might seem trivial because we often assume that these powers come with some kind of built-in instruction manual or the character is smart enough to figure out the key trick on her own, but this is were the trick is. There a really good point in Michael Cricthton's Jurassic Park -- which was kind of present in the movie as well but in a different form -- about knowledge (power in our case) not being equal to discipline.
You know what's wrong with scientific power? It's a form of inherited wealth. And you know what assholes congenitally rich people are. [...] A karate master does not kill people with his bare hands. He does not lose his temper and kill his wife. The person who kills is the person who has no discipline, no restraint, and who has purchased his power in the form of a Saturday night special.
This is, in my opinion, the pivotal point: having power, any kind of power -- being scientific knowledge, the skill to operate and maintain a M-16 or being able to lift a car with one arm -- requires first and foremost the ability to decide when and how to use it. It requires discipline, which is sadly something we, as humans, tend to forget because we rely so much on inherited power. Some skills requires year, decades to master and, by the time you've attained a considerable degree in them you should have also matured the necessary discipline to choose when to use them (I think of martial arts as a common example), but what about skill that can be gained in an instant?
