Ok, you're a fool.
When I was 17 I used to think 23 was really old and 30 was ancient.
50 was so far over the hill I couldn't imagine it.
Now I think of 17 as being just a little kid. Ya think ya know so much about life but in reality there's a whole ton of stuff you don't even realize yet.

Getting old kinda sucks in some ways... mainly cause you lose the groovy things you liked best ...like getting noticed by 17 year old girls, going to parties and realizing that a whole bunch of your favorite artists keep dying on ya... (the guy for boston and george harrison for example) but there's a whole bunch of positives that make up for it. Especially in knowledge about how the world works. Plus, when you get older, all those women you thought were way too old for you start looking pretty good.. so instead of just being attracted to teens, you're attracted to all ages.

Seriously though... 17 is still a baby. There's a long way to go.
