1. That part about it being the worst 4 years of your life was hyperbole, it is what you make of it
2. Some girls don't ski. The ones who do probably won't be at your level
3. Be prepared to be single throughout winter, most girls aren't cool with you being MIA multiple months out of the year. If she is (or even goes on the hill with you) she's a gem and hold on to that shit
4. You'll pay more money for shittier weed as a freshman and sophmore
5. Don't bring weed to school, ever
6. Rushing to lose your virginity will disappoint you in the long run, let the due course run
7. Throwing a house party will fuck your record, you're better off abstaining
8. go to every single fucking house party that is thrown because they are rad
9. if you don't fit in, find where you do and chill with them
10. In reference to #9, being popular high school doesn't mean shit (especially after you graduate)
11. Whatever people do with their own bodies is their business, don't talk shit and people will like you a lot more
12. Don't talk shit and people will like you a lot more (retyping for emphasis)
13. there's a 95% chance you won't meet the love of your life in high school, being single is okay, being tied down is okay, fucking every thing with a heartbeat and a vagina is okay (i recommend the latter)
14. Get a job in summer so you can buy new gear every winter and don't have to bum off your parent's payroll; you can get a dope car too
15. Getting involved with clubs and sports will help you make friends
16. never call a girl a cunt, fat, or a bitch (i learned this the hard way)
there's my .02 feel free to throw yours in
