How do you know that you were right when you labelled a premise "the wrong premise"? How are you sure it is not a case of misdirection and you are looking at the wrong cause?
The answer to these is that you need to be more relaxed in hitching a thought ride. Premise leads to greatness and success if well chosen. It also leads to disaster and destruction, if chosen wrongly. How you know you have the right premise is by what you see ahead and, more importantly, how you feel down inside about what you see.
