My guess is that your Will to Power has no outlet so you are redirecting it into other activities. Forget saving the world; save yourself. Watch the movie Fight Club if you want to see one possible way to do this. What you need is challenge, danger, conflict and conquest -- things which modern society does all it can to suppress and vilify. The result is an epidemic of impotent young men who have neither Will to Power nor willpower. Intelligence isn't enough dude; nerds tend to have little power and be evolutionary failures, so much of what you will read at sites like this probably isn't helpful. Your rational mind is a small component of your psychological makeup, which, if you let it totally dominate you, is unlikely to produce a satisfying existence. Practice exercising your will, over yourself at first, then over your pets, your friends, family, co-workers and so on into the larger world, and I guarantee that you will start to feel much better about yourself!
