What a terrible reason not to do something that makes sense to you. If your success in the startup world is so strongly linked with how others perceive your superficialities, that's not a healthy environment to be in. You might as well add "don't be ugly" too, because everyone knows that beautiful people tend to have more success, and you want to maximize your chances of succeeding.
