If you believe fully in yourself you won't even think about having a backup plan If you really know in your heart that you are doing the right thing, there will be no doubt. If there is doubt, then either it is the wrong path or you are not ready. Your fear is what makes you doubt yourself, and it is this fear that you must overcome first. This fear makes you look for security. The need of a safety net says that you don't believe that you can make it. That creates a self-fulfilling prophecy. If there's no question in your mind then you will proceed as though you've already made it.
