i'm 31 today and feelin' good. i see it as still young with a lot of new and great experiences still ahead of me. i think probably your 30s will be the best of your life seeing as you are a bit wiser and just know more about stuff, you earn a bit more money so can afford a better lifestyle, and finally. actually i can't think of a final point.
other 30 something, how are you finding your 30s? your best years yet?
