You're not clever, pretty, thin, tall, handsome, rich, strong, creative, [fill in your own limitation here__________________] enough to be that?
What if it weren't true?
If you'd like to unlock the doors to everything you have decided it is not possible to be, ask 'What have I decided I can't be?'
Then, if you're willing to see that just because someone else says something is true, doesn't mean it must be true for you, you will no longer be limited by what other people told you you can't be.
You may even (re)discover the greater you, beyond anything you ever imagined. What's right about you that you're not getting?
