That's wrong. If you do not have a talent for something, then the best you can do is to be mediocre. And to get to that mediocre level, you need to become obsessive, so the 'success' will come at the cost of other aspects of life.
Only if you do things in life that you have a talent for, will you ever reach anything above mediocrity. On top of that, focusing on things you have a talent for implies that you will have more time and energy to spend on other things. We only have one life but near endless opportunities and sensations to experience. To throw all that away and focus on one thing is only ever worth it if you have a shot at being the best, at achieving something no one has ever done before.
That makes some of us feel sad working that hard to only accomplish mediocrity, but yeah it is a cruel world. Sounds like you must look amazing and not have to put in much effort. Can you post a pic to show what all this talent has done so far for you.
