Great list. The only thing that I might take issue with is #5: "5. Every decision must be made extremely carefully. Bad decisions cost money."

Taking too much time on decisions is a good way to kill a new company. Many, if not most wrong decisions you can recover from, and it's very difficult to know what the right decision is beforehand. So a lot of the time the "right" decision is just to do _something_ to learn what the real right decision is and then do that.
