I’m not sure I agree, because people might put in the hard work without the psychedelic and not experience the benefit.

Michael Pollan’s “How to change your mind” talks about psychedelic studies where the more effective, longer lasting changes are seen by the people who had more “mystic” experiences.

It’s not just about good intentions, or just taking psychedelics, but seemingly priming your mind to use the psychedelics to (temporarily) change fundamental thought patterns.
