Maybe I'm mentally ill but I don't look fondly back upon my youth hanging out with people. I also feel like life was miserable until I was 35 because that's when I kind of broke free of shitty old habits and thinking and starting making decent money.

I think about it and I regret it. Wish I had been doing more interesting/productive stuff with my time other than getting high/drunk and dicking around. But sadly the option didn't really exist where I grew up, so you had to fill the void.

I also don't get the sentiment of people who like wish they could go back to being a teenager or child. But I like being an adult.
