Congratulations, Heath!
Honestly, the first and foremost thing I'd say is this: your GPA really does matter, so do the best you can. When you graduate, employers will look at your GPA and they will make hiring decisions based on that. It is okay if your grades are not perfect. The better they are, though, the better off you'll likely be.
Other than that, I also say enjoy college. Study hard, but PLAY hard too. TP your roommate's side of the dorm. Snicker and chortle and plot to conquer the planet. Giggle like a schoolgirl every time your professor slips up.
And most importantly, enjoy that damn beer!

College is all about memories and learning. Make your memories, learn your stuff, and get yerself a helluva career, baby.
