I don't know if it was just timing and it jump started a natural part of aging, or if it triggered something that would not have occurred otherwise. Either way it definitely did a number on my 16 year old brain, still unsure if it was a net positive or negative.
The sad part is they don't have such a profound effect on me anymore, it can still be pretty interesting but the life altering trips seem to be reserved for the first few times. My only expectation from them now is to feel nice and have some pleasant visuals. I don't approach it seeking some lesson or greater truth, just have a nice time, which is maybe the final lesson lol.
