The thing is though we don't what many of those people actually wanted, we assume. We assume since they are so good at that, they got to be loving it, but maybe Amy Winehouse would love to be a science fiction author yet she has no talent and picked the easy way out, we just don't know.

I don't want to pick on your particular example but Michael Jordan is known to be insanely practising. He didn't even made to high school ball team the first time around, he practiced that year and got in the next one. Granted he's talented but there's massive amount hard-work behind it. He clearly loved it otherwise presumably he wouldn't spend years on practising.

So following your dreams is not about having talent about something, that talent might not be related with what you love. It's about what your dream is (world domination?) and having background + talent + possibility + luck + determination and so many other stuff like that.

You can't always have what you want but you can get closer.
