I actually had a really hard time turning 30. Didn't happen when I hit 40, but for some reason 30 was a big deal to me. I've talked to others who have felt the same way. My theory goes like this...
Wanna be 13 so you can be a real "teenager"
Wanna be 16 so you can drive
Wanna be 18 so you can vote
Wanna be 21 so you can drink
Wanna be 25 so your insurance rates come down
Then...........
What...wanna be 65 so I can retire?
?
Not sure, 30 is kinda an age I never really thought about making it to, then when I actually made it it was like "Whoa how the hell did I get here, and what to I have to show for it?"
Dunno, just some random thoughts on the subject.
