I'm due in November.
I feel pretty cool about turning 30, actually, I feel like I've met my own expectations of where I should be in life by this time. I'm married, have a stable job, good income (could be so much better but I don't need to save pennies), I feel good about this. My 20s were an insane rollercoaster, I had a blast and also went through depression, and here I am, alive and well.
The key to getting old is feeling good about how much you have accomplished, working hard to meet your own expectations. Now I intend to be at a totally different place when I turn 40, it's gonna take a lot of work but it's definitely doable.
Cheers for all of us 1990 kids, best year to have been born!
