I don’t think anyone can know when you are pursuing something that is really different, like AWS. What I did know from having started businesses before Amazon, as well as from my time at Amazon, was that when you are trying to do something new, it’s really a waste of energy to spend a lot of cycles wondering whether it’s going to be a success or not. We just tried, as much as we could, to stay focused on what we were building instead of wondering whether it would work.
