"Human potential movement" is the term which springs into my mind when I read this. "You can be whoever you want to be!"... Yeah. Of course you can! Apparently, it does not help all that much. Why? Because there aren't that many things you actually WANT to be. In fact, most of the time you don't know who you want to be. This is the real problem.
At some point you may decide to be somebody but over a certain period of time you realise that you want to be somebody else. If you are lucky enough you realise that you just don't want to be anybody other than yourself. Which means employing YOUR unique personal history and your unique genetics - think "natural talents" at this point.
It is exeptionally hard (and therefore useless) to motivate yourself to study financial statements if you are not enjoying it. And you can not like anything. Humans don't work that way. You have certain flexibility but not all that much. So if you don't like - or even LOVE doing something you will never be able to compete with people who do. And using talents FEELS GOOD. Gifted people just LIKE what they do. Period.
So the bad news is that the only way to be successful and ultimately happy is to use your natural talents. The good news is that using your talents actually makes you happy. So the real question is - what are your talents? But that's a whole different issue which still has to be addressed.
