Let's say you have an edge and it works. Do you rest and just execute it and make consistent profits while it is working? or.... Do you persist in your favorite activity and try to improve it? Are you lazy or are you tinkering with something that you do not need to spend your time in? Fix what is already working or leave it alone? Over optimizing is usually performed with forms of curve fitting exercises. I am not talking about that. The quest continues....can humans be perfect? what is Perfect? Michael B. P.S. Tell me some of your stories.
