There is no reason for a plan B as it only distracts from plan A.
For something real to happen we first HAVE to believe it. We must right it down, believe it has already happened and speak it into the Ether. (Look it up) Actionfy it into existence.
All Great accomplishments first were a simple thought passed into the imagination from our creator. I believe this wholeheartedly.
Don't get me wrong, I'm not saying we should not be prepared to survive if something bad happens but if we know we have a plan "B" to fall back on, subconsciously it gives our plan A reason to fail.
