'Yoda Was Wrong'

Stanford University

The Stanford d.school's Bernard Roth, author of "The Achievement Habit," refutes an oft-quoted line by Yoda in the "Star Wars" movie series, "Do. Or do not. There is no try." Roth says there is: "There's really nothing wrong with trying to do something, and there's certainly nothing wrong with doing it. The problem is when you think they're the same thing."
