The New York Times ran an article about Jeri Ellsworth, who recently produced a version of the ancient Commodore 64 computer that runs on one chip. A company has packaged this up into a joystick, and it's now being sold on QVC (search for E22494).
Jeri is a self-taught computer chip designer, who quit high school, but has clearly followed her interest in chip design to the highest level. The article contains a marvelous quote from Andrew Singer, a high-tech executive, who hired Ms. Ellsworth as a consultant: "It's possible to get a credential and not have passion."
How true. How true! Are we doing work that we're passionate about? I can relate to Ms. Ellsworth's resourceful childhood and her deep interest in knowing how her computer worked. She pursued something she was very interested in, and didn't let her lack of a degree keep her from learning, or making a contribution. I admire people like her!
