Hmmm... I have not profited much (not "nothing") from self-help materials, but that is my experience.

Kahneman's book would be fascinating but possibly less practical than Burns'. (I'd like to read Kahneman's book, helpful or not.)

Suggestion: You should be able to find multiple Web reviews of each book you consider. Avoid relying on any one review, but an accumulation of different people's impressions may lead you in good directions.
