excellent post ! when I was young man a good handicapper once told me to just turn the page ! I guess its like that old saying no sense crying about spilled milk ! its hard sometimes ! but just turn the page and look for the next winner .
After the race I look at the lines and my notes to see where I went wrong. There's usually something I overlooked, did not process right, or weighted incorrectly, that logically explains the result. It's a lesson for the future. Then I turn the page.
