What is Power?

Not the definition. I understand power is control. What I'm trying to figure out is what Power means to the person trying to attain it.

Why do some people seek to control more than others?

Why do some people never seem to be satisfied?

Is it possible power is simply about seeking your full potential?

Power is often made out to be an agent of corruption. Is that fair?

They say power over yourself is true power. I agree. Decreasing the power other people have over you allows you to have all the more power over yourself. But do you necessarily need to have power over someone for them to not have power over you?

They also say, those that seek power will never have it. Humility is true Power, forgetting yourself and serving the people is where power lies. But sometimes don't you need more control over your own life before you can help someone elses?
