I don't, and the worst I've been doing dancing for a whole weekend, staying awake until I get visual hallucinations. If I was 20, I would've played video games and worked on software side projects all day. That's what I was doing for the first 6 months of not going to work, after all. But it does depend on the person.
I think if I was 20 and independently wealthy, I would have worked on side projects for 6-18 months until I found something / someone to get sucked into.
But I will agree, it really depends on the person. When you're young and have a lot of energy, drinking 2-3 beers throughout the day might seem like a good idea. I never did; but the fact that many people are blissfully unaware of how 2-3 beers throughout the day impacts them still shocks me.
