I struggled with something similar when I turned 20. Thought my days of messing around were over, time to be a responsible adult. How wrong I was During my twenties I went thru countless relationships, jobs, parties, friends, studies, happiness, bad times and what not. It was a great period in my life, since I wasn't a kid anymore but I was till young and pretty much care-free. Don't worry, you've got a lot of youth still ahead of you.

I used to think when I was younger, that people over 18 were old. Adults. Now that I'm past 30 I think people between 18-25 should be called post-teens.
