There's a great blog post up on the American Express OPEN site by Guy Kawasaki -- it's an interview where Guy asks Hartmut Esslinger (the founder of Frog Design) 10 questions about design. It's a great read, but my favorite is the last paragraph of the article, where in response to Guy's question of what a young person who wants to be a designer should do, Hartmut answers:
"Finally, a young person with the right talents needs to have infinite desire and never give up. I apply a simple test with young students: smash a teapot into pieces and then hand out the glue. Those who rebuild the teapot won’t make it, those who create phantasy animals and spaceships will."
