Maxwell Maltz wrote self-help about self-image, habit and personal change, drawing on his experience as a cosmetic surgeon. Psycho-Cybernetics develops the idea that people act in line with an internal picture of who they are, and that changing this self-image can alter confidence, performance and behaviour. Maltz uses visualisation, mental rehearsal and goal-setting exercises, presenting the mind through the mid-twentieth-century metaphor of a goal-seeking mechanism or “servo-system”. The book has influenced later self-help and performance writing, although its psychological claims and cybernetic analogies should not be treated as a substitute for modern clinical evidence. Maltz sits within classic self-help, positive thinking and performance psychology, with an emphasis on mental rehearsal rather than autobiography or spiritual teaching. Many later coaching and confidence books reuse ideas that Psycho-Cybernetics helped popularise. Read more Less
