Read the excerpt from "On Becoming an Inventor" by Dean
Kamen
From this well-stocked basement came a whole new set of
really neat projects. My younger brother, Mitch, and his
friends, as well as some of my own friends, would come
after school to help. At sixteen I was now a young
entrepreneur, paying them for their help. I was surprised by
the number of orders I was getting for more and more
equipment Soon I didn't have time to build and design new
things. Giving over this work to other kids gave me more
time to do what I wanted to do. This went on after school
and all summer long
