Contrary to what others have said I found all of it especially the last sections very clear. If you compare it to his first book, 'The Disciplined Trader', which I found slightly abstract, this one has been very clearly thought out.
To me the last book lacked structure. I felt the author tried to be a little too deep when it was unnecessary.
"Trading in the Zone" contains all the points from the first book but with far more clarity.
Trading in the Zone and Disciplined Trader seem to go to similar places. The material is useful but Mark is a terrible writer and incredibly tedious to read. The interview about TDT on TASC is actually much more readible and contains most of the material in his books except the prescription for trading through your problems.
See Stocks & Commodities V15:1 (35-40): Mark Douglas and The Disciplined Trader by Thom Hartle at their downloadable pdf bookstore.
"The Way of the Warrior Trader" by Richard McCall. I found his A.C.T.I.O.N plan good when I was suffering from analysis paralysis!
Accept .... all possible losses before entering the battle.
Centre .... yourself in body, mind and spirit.
Trust ....... your warrior skills and instincts.
Imagine ....success clearly in your minds eye.
Only ..........exist in the present moment to control fear.
Never .......stop or look back once action has begun.
