I'm 34, and damn it, this is the BEST time around.
It's the best of all worlds. I still have the energy to hang with the 20 year olds, but I don't have to eat top-ramen, worry about some stupid class, deal with stupid roommates or immature girls.
I got money, an established career, and can really afford any creature comfort or any vacation I want. Basically - everything those young people are striving for.
I can also hang with the older crowd. I have all the things they have in terms of material goods, but shit, I still appreciates my new found semi-wealth. I can play with my friends babies when I need a baby fix. Go wine tasting with them. Whatever.
I am not beaten down by the world yet, but I have already gone through the Socially Awkward Penguin stage. I can discuss stock market trends and how to invest my 401(K) with some people, yet still kick it on reddit and enjoy stupid memes that would confuse 40 year olds. Let's face it, I can watch DuckTales on an nostalgic, and ironic level. How awesome is that?
I play basketball at noon three times a week - but at work on a perfectly manicured campus. I have a fiancee who is cute and fun, but also mature enough to not have to worry about useless drama. I'm not scrambling around, trying to scare a career, but I still am learning quite a bit.
The worst is behind, and the best is yet to come.
P.S: I have copied this comment from reddit because I think this is what you really want to be.
By the way I am 38 years old now. I think this is the best time of my life because I am financially stable and independent. No one is there to put me down or misuse my self.
No one can stop aging but you can be really happy if you managed to achieve things that you need to achieve in certain ages (than typical people).
Be happy bro!
