"Are you thinking that maybe you want to be an astronaut, or an author, or a scientist or a doctor? That's great! And maybe you're not quite up to speed on the centrifugal force of the moon or how many bones are in your arms, but if you believe in yourself, you'll get there. That's the power of yet. You might not be ready for outer space yet, but just work hard and keep your eye on the prize and you'll get to where you want to be!"
