Technically, you are always going your way, which is the right way whether anyone likes it or not. A more difficult form of will power involves the ability to refuse performing a simple favor simply because you decide not to do it. The world doesn't really change. Nobody dies or anything, and you retain a larger sense of freedom. The real advantage, though, is in fleshing out rats.
Ratty people have very few values and almost no insight.
They go around copying other people, and resent terribly someone who doesn't. A decent person likes you or respects you whether you kowtow to their whims or not. Of course, if you exercise your will power from time to time, nobody can ever stick you as a loser. At first, learn to like whatever you're doing. You have to do it in your mind with a recognition that you're not at home, but that you think you are.
