Anyway for me personally the one time I tried acid it was more like: hey cool experience, it feels like I am experiencing things for the first time, kind of like a child. While the trip itself did not really change me a whole lot it made me reexamine things in my life and consider how I approach things and made me more aware of how my emotions and my brain in general can have an effect on my perspective. In that it was a teachable experience and any change in my personality after that experience was due to me having experienced the world in a different way even though it only was once.
I am not planning on taking it again anytime soon though. I can also see how it might affect others differntly, anyway they are mind altering (even if temporary and the changes can be permanent, like a holiday or a car crash and with my limited experience I can not speak to how it could exactly go wrong but I suggest anyone in here respects their mental health and reads up on all this before considering to try it)
