I have been at this so long that I am struggling to come up with an example of why therapy is unnecessary to successful trading. I think it's fine for personal satisfaction in other than trading. Especially if you want to get early parole.
But here is an example of building confidence through simple analyses repeated daily. Attached is my chart for my position trades, plus some market data. I look at it a few times a day for at most 20 seconds. Got it. Move on. Why is it easy? Because I have been doing it forever, and the analysis tool I use isn't half bad. Get a good thing going. Use it. It becomes routine. "Oh, rats! Oil is taking a hit! But it's not in the toilet! Back to trading!"
