Orson, that is exactly my approach.
I honestly can construct ANY argument I want to construct in such a way that I can accept it. My mind is reasonably functional, so I can use to it justify whatever I really want to do, think and believe. Therefore, I use it to seek for ways that contribute to my general happiness and personal growth.
That’s a lot of the approach I take here – to do little more than model how it can be done, at the least, but to show how it can be done and produce real contentment and joy and peace, at the most.
