Enjoy college. Make it an amazing experience. But don't -blam!- around like I did my freshman year, making me graduate with my bachelor's at 24. I should be two years out and a year into grad school right now. Also, if you have extra credits to take classes not in your major, take something interesting, something you never thought you'd take. Try something new. You got this fellow guardian, enjoy some of the best years of your life, because it will be over faster than you know.
