Written by an award-winning aquanaut and with art by a #1 New York Times bestselling illustrator, this inspiring picture book encourages readers to explore their world, build their self-esteem and imagine what they can do and become when they grow up.

When I was young, the world seemed too dangerous. Everything was too hard. I was too young. Places were too far away. But that was okay because I had a big imagination . . .

Through beautiful, spare text, Jill Heinerth tells her story about a girl who feels too young, too little and too far away from her dreams. But you don't need to wait to grow up. It doesn't take much to imagine all the things you can do and be. What if your bedroom were a space station? What would it be like to have flippers or tusks? In your own home you can explore new worlds and meet new friends.

Jaime Kim's luminous art transports readers back and forth through time to see how Jill's imagination as a young girl laid the pathway to her accomplishments and experiences as an underwater explorer.
