"Q: What do you wish you had done differently in the Smalltalk era?

A: I had the world's greatest group, and I should have made the
world's two greatest groups. I didn't realize there are benefits to
having real implementers and real users, and there are benefits to
starting from scratch every few months. I hired finishers because I'm
a good starter and a poor finisher, but it took me a long time to
realize that I was interfering with them by trying to improve things."
