I went to a Vipassana retreat [1] for the 4th time in my life (over a 10 year period). It has been a while, last time since 2016. It's hard to keep up a practice, but I'm in a position to do so now that's must better suited than before. I can't go into that, since I want to keep this comment short ;-)
I've noticed a few things:
- I experience pleasant, neutral and unpleasant feelings more intensely.
- I am better capable of not reacting to my feelings (I have more choice in it). This is both needed with pleasant and unpleasant feelings as both types of feelings can come from (un)wholesome places. E.g. pleasant/unwholesome: alcohol or watching YouTube for way too long. E.g. unpleasant/wholesome: you're noticing work is boring you at the moment. You realize that you're a bit tired and could use a nap in order to feel more sharp.
- I react more intuitively to people their body language, without realizing it much myself
In short: it makes me feel more alive (quality of life has gone up) and it makes me feel more at ease around people.
There's a reason I nicknamed myself mettamage. This is the reason. Meditation (metta meditation being one of them) has changed my life so much that it has become my pseudonym on HN.

Note: the practice is awesome. I'm not a fan of that they dive into Buddhist scripture that much. Fortunately, whenever they have their videos on, you can just meditate through it. More fortunately, they do mention at one of their last videos that the practice is what is important: understanding the theory that is unrelated to the practice is not important.
Examples of what I don't / do believe: I don't believe in water, fire, earth and air being the core elements of the world. I don't believe the Buddha was able to notice subatomic vibrations. However, I do think that the craving/aversion framework is a useful one. I do believe that meditation can teach you a thing or two about addiction and how to overcome it.
