It's not so much hype as lack of precision. Robbins tends to specify procedures in huge "steps" like, "step 1: cultivate a great life". (I exaggerate, but not by that much.)

That's odd - I didn't get that at all, and I found that he had a lot of advice about various concrete techniques. Off the top of my head: pattern interrupts, morning questions, evening questions, setback questions, smiling, re-imagining negative memories, gathering references, changing your mental vocabulary.
