What is it like to be 30-something?

I’m turning 30 next year! I greatly enjoyed my 20’s and will definetly miss being 20-something. But the closer I get to 30, the less I am afraid of turning 30. My sister, who is 28, commented to me: “Is it just me, or do 30-somethings look much younger these days?” This made me feel a little better. Her comment made me think about my experiences looking through old year books – everyone looked so much older back then. One time I looked through a college year book from the 1950’s and all the people in there looked like they were close to, well, my parents’ age. Now when I see college students, they all look like high school students! Do people really change for the better in their 30’s (in other words, does life get better)? I always heard that women in their 30’s have more confidence, care less about what people think, and have better sex. Is this true? One reason I do look forward to turning 30 is that I want to advance in my career and I think being older will help my professional image. Although I’ve always been very ambitious and have done quite well for myself in my 20’s, I feel that being young created sort of a glass ceiling for me in terms of my career. What’s your experience turning 30? How should I celebrate my final months as a 20-something? Or, perhaps, how should I celebrate turning 30?
