JESUS, I started college 9 years ago. F.M.Life. Holy hell I'm old. Seems like just yesterday I was pounding drinks with friends and roaming for house parties.
Honestly man cherish this moment. You are literally on the verge of what very likely will/can be the very best years of your life, and you're right at the leading edge of it, which could easily be classified as the best part of the entire experience.
Your first few weeks you will be meeting everyone in your dorms, your doors will all be open and it will more or less be a walk in free for all with booze, houseparties and basement keggers with beer pong, and sex and random hookups and puking mixed in.
You are going to love every minute of it. Savor it. You've got lots of 18 year old girls (oh how young that sounds to me now that I'm an old man of 27 who couldn't possibly touch one today, but I realize back then they seemed like old adults) who've never been away from home, the testosterone, estrogen, and desire to go wild and play and live the college life away from mom and dad and needing to sneak around and listen for the garage door opening are going to be pumping and it's going to be a fantastic time in your life.
Enjoy every minute, and my word of advice--get student season passes to the hockey/football games (I was at a great engineering school but also was a Big Ten school and one of the largest schools in the country) and tailgate at 7 AM with the best of em, and put flasks in your hoodie on the way into the stadium. My big regret in college was not doing this, but towards the end I went to the games with people and joined in and wished to God I had done it all a long, even though I never gave a rat's ass about sports. That said, Gopher hockey is great.
Bust your ass M-F with classes and don't get distracted (except for those $1.25 PITCHERS on Tuesdays and Ladies night on Wednesdays...) and then let loose on the weekend.
The trick to college is balance. I'm 27 and lived at home the first two years unfortunately and busted ass and didn't touch booze until I was 20 (really), but ten years later look at me ramble on here about the golden era like I'm an old blue-hair remembering the good ol' days...it's obvious I didn't have as much fun as I wanted/should have, because it's not out of my system, which is kind of sad, lol. But--I did well and don't regret it, and have landed a good job and have a good life today. Raping my classes the first year I was there and floating my GPA on those made a big difference I feel. In other words, it's crucial to do well your first year because every semester after that will affect your GPA less, meaning NAIL your classes the first year and ride that GPA out the door three years later. By the time you're a senior, your grades will have little affect on your GPA, even if you have a bad semester of tough classes. Likewise, a good semester will do little to raise a bad GPA. So my advice, be serious M-F, and then let loose. Balance is key, the anxiety will fade. I've been an anxiety nut my whole life and I loved it even when I hated it.
I wonder if I could still work my way through the crowd to the keg in a musty basement with a $5 cup and just feign being a grad student???
