What if your best isn't good enough?

wondering:

Now, I know about all the Tony Robbins stuff, positive thinking, all that. And I've done that. Got up, dusted myself off, tried again using what I've learned from the previous attempt.

But, what if that isn't enough?

Is there some "magic", some unlearnable, some got to be born with ingredient that either you have or you don't? Is there luck involved? Is it all about family connections?
