The biggest thing for you to realize is that you can absolutely do any of those things. But you can probably only do one or two of them. Spreading your efforts around is going to get you mediocre everything, which may be okay, but if you want to be truly excellent you need to focus and concentrate on what's important. Life is about prioritization. Somehow the message that "you can be anything you want" has gotten turned into "you can be everything you want" and that's just not realistic.
