"You have to be willing to make mistakes regularly; there is nothing wrong with it. ...making your best judgement, being wrong, making your next best judgement, being wrong, making your third best judgement, and then doubling your money"
Its not about the money, its about planning for both possibilities and sticking to that plan without rationalizing. I call it how I see it. When I'm wrong I accept that reality, and find something else to be right about.
