The only thing that changed for me around my 30th was my metabolism, I don’t lose weight just by wishing it and hangovers get worse, other than that; I love this decade about as much as the first 3.
Happy Birthday!
Well, the “67” should have been a hint. :dubious: Out of curiosity: How old did you think I was? (I’ve mentioned my age before.)
I’ll send you a picture; oughta kill that off pretty quick. 
Thank you, I love it!
jackdavinci, I’m a straight woman… which makes me 10 in gay years, right?! 
Thank god, because I really wanted a pony for my birthday but feel foolish asking for one at 30.
You are 30. You look totally hot. You’re damn smart (Evidence: You are here.)
And what do you have in life? Maybe not all you want, but do you have all you need plus some? Do you have people you love & who love you?
You’ll be fine! BIG HUG!
Now, if you’re in the same condition when you’re 40, then it’s over!
46 here.
blush Thanks on all counts. I really did have a swell birthday and I felt more grateful for all of the people in my life than I ever remember feeling previously. My life certainly isn’t where I thought it’d be by 30, but then I had no idea how difficult being an adult would be. Looking back and knowing what I know now, I think I’ve built a pretty cool existence thus far.
I’ve also been cognisant of junk food for two days straight, which is something brand new and completely unexpected. I blame a deep-seated fear of turning into Wilford Brimley.
I have the first real career I’ve had in my life (with fantastic management that appreciates everything I do and our worst deadwood taking the hike in a month). I have a fantastic car that gets 30 miles a gallon under the worst conditions and handles like a dream. I have the fastest, most powerful, most reliable, and safest (CA Security rocks) computer setup I’ve had in my life, not to mention an Internet hookup that recetly went from really fast to incredibly fast. I’m going on an all-expenses paid Las Vegas vacation this Thanksgiving holiday.
None of this was true two years ago, let alone before I was 30. IIRC, I was largely preoccupied by whether the hell I’d get a steady job and why my house had to host so many damn noisy parties.
You’ll be fine. 
Your thirties are just the beginning!
On my thirtieth birthday I got up early and danced while I watched the sunrise on the beach. It was glorious!
I didn’t begin to get my footing until my thirties. And my forties were even better!
Swear your independence and loyalty to yourself no matter what and you will do just fine. Keep your sense of humor and love with all the stops pulled out!
I turned 30 in Bangkok. Suffice to say, it was a great time. It was all smooth sailing after that, too.
Happy Birthday, young 'un!
But:
You get taken (more) seriously
The money’s better
The sex is better - you now have some perspectives on what romance/love is, and simply humping due to hormonal rage has past (or, at least, pray to whatevey you hold holy that it has).
You (really should) know how/when/why to pick fights - kids fight for stupid, self-destructive reasons. You’re past that, right? Right?
Your peak age (40-45 (yes, really)) is that much closer.
and,. mostly:
There ain’t all that much you can do about it, so do the mature thing and RELAX & ENJOY, fer cryin’ out loud…
You’ll live.
I turn 60 in December. If I can do it, anyone can do it.
You know, it totally depends on the person.
I’m in a new job I hate where at 36 (it’s my birthday this weekend…which also sucks) I’m the youngest manager in the group as well as the youngest employee. The people I work with are OLD. Maybe not chronologically, but in spirit. Dull, inflexible, unmotivated, tired, basically everything you dread about being when you turn X years old when you are X-1 years old. It makes working there utterly miserable.
At my last job, there were a lot more 20-somethings and 30 somethings and quite frankly, I like having the younger folks around. It tends to make everyone more youthful and dynamic, whether it’s going to one of the interns 21st birthday party in Murry Hill or my 37 year old managing director’s house partys in the West Village or the wacky old 60-year old partner who seems to know everything about everything and has a crazy story to go with it.
At my age, I would much rather be the Racer X cool older brother type than the “young hotshot kid” in a group of Mr Burns’.
Yes, there are physiological changes as you get older. However I meet too many people at all ages who use age as an excuse of letting their life fall into a boring rut. It’s pretty much up to you.
Did I mention my friends and I went on Spring Break when I was 21, 22 and 32 years old?
The husband was taking it hard when his thirtyith birthday rolled around, so we held him a funeral. The friends came over and delivered euologies, we watched “Better Off Dead.” He felt better.
