Historically, whenever I have a killer morning, I tend to get sloppy with trades in the afternoon, and not unlike many others, tend to give much back. It is a trait of a poor trader to want to be in "the game" all the time.
Not trading is a bit contrary to the efforts that generally bring success in other occupations where "keeping at it" leads to reward.
Not trading is a difficult thing to do for some of us, especially slow learners like me.
