i dunno, i guess since i'm 22, I haven't experienced everything you've talked about, I haven't finished undergrad yet either, but myself, i'm a person that's constantly evolving, and think i'll probably continue with this for a few more years.... but then i look at my sisters, they're 26 and 29 and their jobs have changed, their friends have changed.... they've settled in certain things, but continue to strive for change and better in other situations... and i don't think that up until you're 22 things are constantly changing, i think once you hit high school and college, things start to change, but before high school, my life was pretty steady and never changing, i had the same friends since elementary school.. shit like that...
