well what he's trying to say is from 16 on up you get more work.... and it's true you dont seem to care about school until your 16-19 years old ....cause you want to work hard and get into a decent college/University......my last years of highschool were very stressful for me :(
Lol, my last 2 years of HS were the easiest - especially senior year, they let us get away w/ so much, had one less class, etc. First year of college was a breaze too - all downhill from there though.
