An Entrepreneurs Life has a great round-up how to deal with your critics.

"One of my mentors is fond of saying, "if you don't offend at least two people a day, you aren't saying anything."

"I don't know about the number, but I do know the only way to not be criticized is to do nothing. To say nothing. And to be nothing. To cower into the shadows, and hide who you are."

"A lesson new entrepreneurs often find difficult to take is this: No matter what you do or how well you do it, there will be people who criticize you, do not like you, do not like the way you do business, and do not like your product. This is a truth of entrepreneurship. It is something you must accept and embrace."
