Drunken, joyful reverie without inhibition is living poetry. Sobriety is admirable, important, and just. But no, you did not 'do all of those things'.
But now that I'm in my 30's and comfortable being open in just about any social situation, I don't find that alcohol adds much. I can lower my inhibitions on my own.
The way life turned out though, I'm not in touch with any of those people anymore. The idea of >"You get tired, you say goodbye to the people still staying out, you go home, drink water, and go to bed." sounds amazing, because I have energy to do personally rewarding things the next day without feeling wiped out and hungover.
There are sober people at burning man.
Anecdotally, at 35 I still sometimes wake up at 2 and stay up until sunrise thinking of cool new ideas.
Sounds like the perfect ending to a nice evening, where's the problem? Fear of missing out?
