It sounds simple enough, but ideas are often so ingrained in our heads that it's easy to get lost in your own opinions. During a Q&A session at 37 Signals, Bezos shares this insight:
The idea is that you should consider your point of view as temporary. It's always changing, and if you come to a point where you want to go back and re-evaluate an idea, that's not a bad thing. We're all wrong a lot of the time, and backtracking on an opinion shows that you're open to new ideas that challenge the way you view the world. After all, remember that, "only imbeciles never change their minds."
