What was it?
Hey! Guess what? Your heart might be right. Let her talk a little longer. Disengage your brain and let your heart, your soul, the part of you who's still allowed to dream, imagine and wonder, speak to you. She's there for a reason, that little voice who's urging you to go try something new, something out of your comfort zone, something exciting that will open you to new possibilities, new friendships, new inspiration, new everything.
Learn to shut down the negativity that tells you You couldn't make it. You can't get there. You shouldn't do such a thing. (That one you may want to give a share of your earspace if there are legal or moral implications involved in what your heart wants to do). You'd never be able to pull that off ... They'd laugh at you... You wouldn't fit in... What if they don't like me ...
SHUT. IT. DOWN, GIRL.
Learn, by this new experience you're going to say Yes to, that trying and succeeding will delight you, fill you with an amazing sense of accomplishment and pride, and give you more confidence to try the next thing. Or that trying and failing will make you stronger, not weaker. (But really? There's no such thing as failure. There's only new experience that teaches, if you're willing to learn and not give up.)
Grow yourself through stretching and trying and busting through all of your fear and doubt and negativity. Grow yourself by proving your internal nay-sayers wrong. Grow yourself by learning that YOU are bigger, tougher, braver, smarter, stronger, than you've ever believed. Grow by exposing yourself to other people who will believe in you, too. Grow yourself because you ARE capable and worthy.
Go do it.
Go say YES.
This one time. I promise you will never regret it. And you will say YES again because of it. There'll be a whole happy YES chain reaction.
