The cure for insanity is to simply know when you are being insane. Since insanity is doing the same thing over and over again and expecting a different result (Einstein); then you need to be acutely honest with your self.
Is there an open door that you are afraid to walk through, a phone call you don’t want to make, an exercise regime you don’t want to start, a class you know you should take. If you are afraid, find a friend to help you walk through that door, do what ever it takes.
Conversely, is there a craving that you can’t help but satisfy? Greed can cause us to stumble over the rock over and over again. If you can”t help yourself, find a friend to steady you on this narrow and rocky road, don’t be insanely proud… do whatever it takes.
