Perhaps I can provide an example. One trader sent me his monthly review of his trading. It was two pages, had no specific reviews of trades, had no detailed statistics on his trading, and finished with a general goal to be more selective in the taking of trades. Another trader sent a review for the same month. It ran over 200 pages. It detailed every trade made, what was done well, and what could have been done better. The first trader meets with me occasionally. The second one has been meeting with me every week, focusing on the most recent lessons learned and improvements made. The first trader is looking to make money. The second trader is like the flower: just blooming.
My son Macrae and I have been taking lessons in archery. It's an interesting sport; one I've never given much thought to. A big part of success is learning the correct form for each phase of the shooting process and then replicating that form with precision. There are adjustments to be made when changing distance, changing targets, etc., but the key to success lies in unusual self-control. Psychology is important to archery performance, particularly in stilling the mind and staying focused on the target. But psychology cannot substitute for good form and continuous learning and practice.
So it is in the trading world.
