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.

What can you conclude about Dean from the excerpt?

His ultimate goal was to create jobs for his brother and his friends.
His main interest was designing and inventing new things.
He lacked the motivation to build the equipment by himself.
He valued money more than he valued his brother and friends.
