Ah... I'm still in my twenties, but not for long. Would love a re-do of my earlier ones (20/21, but hindsight is 20/20!), but 22 is when my life really started (moved to New Zealand to be with the most wonderful hubby ever!).
I'd say my 20s were pretty good to me. Not looking forward to my 30s. That's the time I have to think about kids and getting a real job (I'm in school -again- studying to be a teacher). Though, someone did tell me that growing old is mandatory but growing up is optional.
