I dunno. Psychs have taught/shown me valuable things, but a lot of it, I suppose, is part of growing older and hopefully having become more mature. It's hard to decouple what changed due to psychedelics, and what changed due to those other factors. But to me, they have been a positive influence, 100% certain.
Still do not know of any better ways to have a deep hard look at life/existence, nor do I know of a better way to be bluntly reminded that just being alive is a miracle in itself, and there is beauty everywhere one looks.
I wish that knowledge would stay with me longer, it does tend to become intellectual knowledge and not really felt, after awhile.
(And yes, tripping again will usually bring it back, but I wonder if somehow this could become "stable" knowledge, and how to get there. Perhaps here is the value of a spiritual path, others feel free to comment..)
And so, to address the original questions;
1) Memory can be tricky, but thinking back to my 1st major psychedelic experience (with LSD; there had been Salvia experiments before, but it was just weird, no insight.. you know the stories), there was an acute realization that there is much more to perception than meets the eye. What I took from it (after eternal moments of beauty) was, pay attention to the present. Pay attention to now. It is all you have, it is all you'll ever have.
The same message I had been reading about in Buddhist teachings. The same message wise elders spoke about. And at that moment, I understood it,
I felt it.
Wish I could tell you guys that such a realization (not that uncommon on acid, I hear) stuck and my life was forever changed due to it, but it would be a lie.
My life was forever changed in the sense that the things I witnessed that sunny afternoon in my modest apartment confirmed, in ways that I would not, could not, have suspected before, that there is value and much learning in this psychedelic path.
Not blaming anyone or anything, but in retrospect it seems that not having people around (physically) whom I could talk to about this experience (without them thinking I lost my marbles:grin

greatly attenuated the benefits of the experience.
None of my friends/family back home trips, a few listen sympathetically, but nobody
understands. Part of it was my own fault of course, but it's part of growing up. I had to learn how to
find like-minded people.
In that frame, after having had several friends/family members question my sanity as a result of trying to explain the things I'd experienced, life eventually kept going more or less in the direction that it already was.
Having tripped a few dozen times more since then, I would say that, at least for me, the realizations/insights soon fade unless concrete action is applied to make them a reality. To aid this process I keep a trip journal, and make a point of sharing experiences with friends (who do trip and thus can relate) online. I think this is a pretty common thing?
So to me, given such conditions, the result has mostly been, in what is perhaps an ironic twist, a strenghtening of the ego, due to the need to keep 'psychedelic nexalizer' segregated from 'people think this is normal nexalizer' in public.
I found that it is pretty impossible to discuss these things (that interest me so much) with 98% of the people I know (in meatland). After trying, perhaps a tad too enthusiastically, to tell my social network about those wonderful tools, I quickly came to realize the futileness of the endeavour.
And thus it was concluded that I had to go elsewhere and meet more like-minded people.
If you've read this far, hopefully you can by now see the progression to the answer to question #1; Psychs brought great destabilization and a much increased awareness of just how out of my environment I was at my residence. Don't get me wrong, it's a nice place, good weather, nice nature, but ... I don't have anything in common with anyone there besides the 'normal' society-expected things.
And it is nice, people are nice, it keeps things flowing, but it doesn't scratch very deep.
To some extend I already knew it, but after taking psychedelics, it was undeniable.
And though I'm still living through the repercussions, and frankly a bit lost, it was something necessary, and one day it will pass.
And thus I travel and explore.. inner and outer.
Regarding #2, that's easy (even though, again, in my particular case this awareness predates psychedelics): No.
I would rather endure suffering and questioning and false starts in the search for how to live the life I truly desire to live, rather than always being in my comfort zone and not thinking about these things.
Have I succeeded? Partially. The last few years offered stability, but now reaching my 30th birthday I realize that a lot of what was built doesn't make sense anymore, and/or has to go, and new structures need to be formed and nurtured.
I don't always manage to live up to the idealized version of myself, and psychedelics actually tend to make that so much more visible. But in the middle of it I learned to accept it better.
As for your last (big) paragraph, that is how I've always felt, even before cannabis. The internet has been the miracle of my life, for suddenly there ARE so many people out there interested in the same 'crazy' stuff.
But over my 20's I realized that it's not enough. This virtual world of ours only goes so far, and real human interaction is necessary. It is an amazing place and I can't imagine my life without it (and offtopic, it bothers me to no end that almost nobody can see the damage being inflicted on it
right now- I speak of course of mass surveillance)
I too am searching, and in my personal writings, I often ask the questions; Here are some tentative answers..
"Who am I?" ---> That which can see (some) possibilities unfolding before they do; That which can (possibly) make them come to be.
That which can to some extent select the reality to be experienced; Awareness.
"Why am I here?" ---> To learn, to improve, to experience, and discover, explore. To live well.
"What is the purpose/meaning of living?" ---> To LIVE!
This is the time to really find out who you are and enjoy every moment you have. Take advantage of it.
