Jarrett J. Krosoczka is a children's book author and illustrator who created the Lunch Lady series of graphic novels - and he has a powerful story of his own.

The child of a single-parent heroin addict, he was brought up by his grandparents, and his best friends, he says, were characters in books.

His story about how he became an artist and an author was performed at TedxNew HampshireHampshireCollege, and has just been posted online. It's a powerful tale of the importance of creativity and imagination.
