For the hiring tip, you say "don't hire friends" and then immediately after "in some cases it worked out great". Perhaps could use an example of how this was #1 on your list of 3 worst mistakes.
#2, don't raise money too early. And then you say you actually backed out of the deal and didn't raise money after all. So this #2 greatest mistake didn't happen to you but almost did?
I guess things are going so great you are having trouble finding some things that went wrong?
