First, your idea has to be big enough to justify devoting your life to it. Make sure it has the potential to be huge. Second, it should be unique. When people see what you are offering, they should say to themselves, “My gosh, I need this. I’ve been waiting for this. This really appeals to me.” Without that “aha!” you are wasting your time. Third, your timing must be right. The world actually doesn’t like pioneers, so if you are too early, your risk of failure is high. The market you are targeting should be lifting off with enough momentum to help make you successful.
