Why do people who have no skill/training/in-depth knowledge in the subject they have ideas about, feel that they qualify for being entrepreneurs/start-up founders and deserve success? I'm not saying that you have to have a totally profound knowledge of the subject of your idea, but you should be at least interested enough to make a huge personal effort to acquire a deep knowledge. Why? because you have no chance in hell of succeeding if you don't know what you are talking about. Hands-off ideas people do not derserve success in my book: the idea is not the thing, the implementation is, and you don't get to lead if you can't take part in/understand the implementation. If there is one lesson that business in "The Silicon Valley Era" should teach us - it's this lesson.
