Yeah that is why he said it is a bit of a lottery. 2 of 9 seems like a pretty solid success rate but that means even you (someone who has a knack for it) would need 4 solid efforts to have good odds at getting a winner. 4 failed attempts is going to burn most people out emotionally if not financially. Was your first successful business one of your first ones? What if it had taken you until your 6th try to get a winner? Would you have stuck it out?
