Two big things—no homework, and fixed hours. No homework is awesome, obviously. But having fixed hours was an adjustment after getting used to being able to set my own class schedule at the beginning of each semester and spending my time however I wanted. It takes more discipline when you're expected to be at your job from 8 to 5 (or whatever your set hours may be) each day. Beyond that, I'd just say there's an increased sense of responsibility. College prepares you for the real world in some ways, but it's not the real world. There have been things I've learned since graduating that have made me say, "What? How did I not know that?" But you experience stuff, you sometimes make mistakes, and you move on. And life keeps going on, which is nice.
