15 years from now...

So you're a freshman now.  New territory, new faces, and new sense of purpose, right? I didn't think so then, either.  It'll be the same classmates you've had since grade school, clustered with a few you've never seen in your life, huddled into classrooms to backtrack the same shit for the first nine weeks.

I don't want to warn you about the importance of grades.  No need.  Without any real studying or effort, I was in the top 25 of my class, so just coast like we always do and you'll be fine.

I could tell you the successes of business, like who to buy stock from, but money won't change the fact that there's a more pressing issue.

Yeah, THAT thing.  That thing we dealt with for years, it seems.  Let's deal with that, and now instead of later.  Literally everything, physical and emotional, will be resolved in what took me about an hour to fix.  Drugs can help but aren't necessary, at least not for me.

I know neither of us want to talk about that, so moving on (so long as you get on it ASAP).

We are truly terrible on judging character in people.  Ditch that kid with a temper; he gives nothing in return. And play with Fire.  You'll know what that means.  It's a damn shame I didn't learn the truth of that until just a few years ago. 

Other than that, you're on your own.  Consider those points; your life will be exponentially more enjoyable.
