"You never, ever, ever second guess yourself when you’re the boss. You can’t afford to."To which I say "Nay!"- Matt
If you don't have someone to second-guess you, you will make the same mistakes over and over again. Yes it is important to stand to your decisions as a guild or raid leader, otherwise people will lose all respect for you. But you can't do everything right. As much as you think decisions through beforehand, you have to accept the fact that you will make mistakes. Making mistakes is human and isn't a problem at all, the problem is when people don't learn from their mistakes. But how would you ever notice your mistakes without being second-guessed? You can't.
