In contrast to the fabled “freshman five,” here is a “freshman 15” that is really good for all first-year college students (and high school students, and grad students, and well, anyone).
Pastor Jeff Brewer suggests 15 ways to glorify God as an incoming freshman. If the first principle is practiced well, then the others will follow:
1. There is no greater way you can spend your time, energy, and effort than pursuing Christ with all your heart. Education matters. That’s why you’re going to college. But pursuing Christ matters more. Remember, you can make only one thing your central aim in life. Make it the right thing. Ask God for much grace to keep him at the center.
Words of Grace 
This is such a great list. I really love the first 3. They are even part of the “15” I use in my Bible study, The Freshman 15.
