I am 75% to completing it, and already implementing plans to remake myself in life and trading.
The ideas presented in Chapter 3 (The Golden Rule on Habit Change- Why Transformation Occurs) makes me think that it is possible to create automatic habit loops for trading, and to avoid mistakes, when "...during crucial, high-stress moments, everything would fall apart".
In Chapter 5, on Willpower, it is mentioned of patients recovering from hip or knee surgery that "...plans were built around inflection points when they knew their pain—and thus the temptation to quit—would be strongest. The patients were telling themselves how they were going to make it over the hump.". Again, I think this may be applicable to trading - where precise plans should be made ahead of time, such that the pre-determined reaction to market events is deliberate and automatic. By pre-determined I mean a considered, specific approach, as opposed to a panicky knee-jerk reaction.
