 It doesn't matter whether you become a doctor or a politician or a yogi or what the hell you become is not the thing. Success means you are living your life to your full potential. You should not be aspiring for success, it's a miserable way to structure your life. You will simply cause pain and suffering to yourself and suffering to everybody. So do not ever think of success, just see how to make this into a full-fledged being. This will find expression, if it finds good expression people around you will say oh he is a great success.
