For those that haven't tried psychedelics but are curious about them in a personal growth / non-recreational way, on the Joe Rogan podcast I heard a good metaphor along these lines:
Imagine your brain as a snowy hill. Each decision you make is like sledding down the hill, causing a slight indentation in the snow. The more times you make a decision, the deeper the groove, the faster you make the decision and the harder it is to try something different and escape the groove. Psychedelics is like fresh powder on the hill won't the grooves away so you can try new ways of thinking / new routes down the hill.
