I Can Make You Happy

McKenna has a real audience and a proven format, and readers who click with his hypnosis-based approach often report meaningful results — the CD component is a thoughtful addition that puts the technique into practice. The problem is the Publishers Weekly critique lands squarely: the coverage of brain chemistry, yoga, and mindfulness is superficial enough to undercut the credibility of the broader argument. Fans of McKenna's previous work will find this familiar; newcomers may be better served by a more rigorously researched happiness title.
