I took a computer-science course to fill a prerequisite at Stanford, and I realized that every day was a new problem, and every day you got to think about how to solve something new, how to reason through something new, how to develop an algorithm to solve for something you hadn't worked on before.
I started studying shyness in adults in 1972. Shyness operates at so many different levels. Out of that research came the Stanford shyness clinic in 1977.
We had this thing at Stanford called the 'Campus Loop,' and then we had another run called 'The Dish,' and you'd run up to this giant satellite dish, which was probably extremely unhealthy. I would do those two runs, and I just found it so therapeutic. My girlfriends and I would have these great conversations about guys and school and life.
