Finally, I think I understand my frustration with trading.
I think realists just see the world as it is, and jump in and deal with all the good and bad, and roll with the punches.
I, and many others, may be perfectionsists and idealists, and are offended by the messy nature of the markets, and look for aesthetics, beauty in the untidy action. I think thats why many are attracted to the esoteric, mystical, mathematical perfection, which may actually not exist. Losses are an offence against the musical beauty.
Well, markets are messy, and its OK to be messy.
I dont have to be perfect. As long as I brush my teeth and take a shower once a day, and chew with my mouth closed, I can pass for bearable. Doesnt matter if I get a few things wrong now and then. Same with my trading.
I am not brilliant, but I actually make money. Losses still hurt.
But I follow principles which keep me in at low-risk.
