 My biggest failure was actually a small personal robotics company that I tried to do in the early 80s. And the idea was sound. The market wanted something like I was describing. The technology just would not allow me. Getting your idea at the right time is really important, because if it's at the wrong time, all you can do is wait. Like right now, I think if I were to try to do my robot company again, I think it would be a massive success.
