Yes I have read all of her books, they were useful to me. It helped me to locate the specific traumatic experiences and social/educational conditioning that were causing me permanent anxiety and poor trading system execution. Then I brainwashed myself to erase my own self-defeating negative beliefs with other more positive and productive ones, following Ruth's advice. I am now happier, at peace with myself, and profitable. But it's a permanent process, it seems like it's human nature to go back to negative beliefs, so I subject myself to permanent introspection while trading to analyze my beliefs and keeping them positive. Mark Douglas's book made me realize I had a psychological problem (LMAO) I started to work on it. Ruth's book went into more specific issues and ways to work around them.
