How do you deal with negative feedback?
You learn from it. Often it starts a line of development: Well, yes, that person said they want a light vacuum, which is impossible, because motors are very heavy. So you say, “We might develop light electric motors—no one’s ever done it before; we must do it.” About 18 years ago, we set off on that journey. It took us 15 years before we launched a revolutionary small, light motor. Negative feedback is really interesting. I enjoy it in a masochistic way.
