Why? If you wouldn't do them later in life, why would you do them in your 20s either? Unless you mean things like claiming to be 23, which would be dishonest if you weren't.
No man, partying 6 nights in a row, hanging out being care free, living for the moment etc. So if someone asks you, how were your 20s, you smile and say wooh, they were good, and off record. :-)
Basically I'm saying party it up, learn a bit about everything and everyone, back pack across a continent or two, and don't be in such a rush to jump in the rat race. When you're in your late 20s, dropping everything and rolling out will most likely be near impossible. You will be more rooted like an older tree. Right now just see and feel the world you have come into and just play with it.
My 2 cents.
P.S. to me a Michael Jackson or Mark Zuckerberg are not a great life, because they were/are unidimensional. They are what they are and not much outside of it. In technology, a rounded and balanced figure I can think of Steve Jobs. He got the fuck out, then got back in. In is always there, you can always get back in, but you can't always get out.

If those are good things to do, why are they not good when you're not in your 20s? If they're not good things to do, why would they be good in your 20s?
They sound kind of like stupid, boring wastes of time to me. But if they genuinely make you happy, why would they stop genuinely making you happy because your hair fell out and you got fat?

When I was 29 I quit my job, and then digitized the Oxford English Dictionary, published my first peer-reviewed paper, moved into a Volkswagen bus, drove all over the country with my wife (having to learn to rebuild the van's engine in the process), and moved to Argentina.
You can live a cliché, but you don't have to.

Given that statement, I'd bet money you don't know Zuck personally.
