I highly recommend trying mushrooms or acid for someone in a good place mentally who wants to improve themselves. Obviously one should do their own research for responsible consumption, and find a good set and setting.

I went from drinking a consistent 1-2 alcoholic drinks a day (very rarely getting drunk tho, just loved homebrewing and craft beer), being nearly obese, with little cardiovascular/muscular fitness to being in a much better place. I now exercise regularly, have a resting heart rate of 54 bpm, lost 30 pounds, meditate every day, eat much more healthfully, rarely consume alcohol, and I am more patient and listen to my partner better.

The increased neuroplasticity caused by physcadelics when combined with a desire to improve habits is a very powerful combination.

There is also a legal, mushroom based therapy for anxiety and depression that has shown great results, available in Oregon.

I really do believe society is much too welcoming of alcohol consumption, and much too resistant to physcadelics. We got this one so wrong.

I sense judgement from you towards anyone who has found utility or enlightenment through mind-altering drugs.

Just because I'm smart doesn't mean I stop reading. Just because I am fit doesn't mean I stop running. Just because I'm happy doesn't mean I can't dabble with new mental models.

And finally, to clarify the OP's statement: "Mind in the right place" doesn't mean being perfectly happy or without stressors/depression. To me it suggests someone doesn't have mental illness or suicidal tendencies.

You do if you want to "see for yourself". Which was GPs entire point.
