When you change your focus to your purpose, you stop worrying about how much money you're going to make and your job title because those things to some degree are irrelevant if you don't love your work.
A man cannot be comfortable without his own approval. There is nothing more satisfying than that sense of being completely "at home" in your own skin. When you achieve that as a natural state of "being", then you can finally look beyond yourself and fully contribute all your talents to the world.
