Well that's a good attitude and will help a lot gaining you more experience. More new drivers should think like you. And its true, your real-world learning will begin now.
One of the best things that I can think of is to practice "dangerous" driving, in a safe enviornment. Like, after a snowstorm, go into a snowcovered parking lot and practice skidding and fishtailing. You don';t have to go fast but just get the car in a low speed skid and learn how to fell it when it happens and even how to recover from it. Be sure the lot doesn't have those cement parking bumpers, though, and practice in the center, away from obstacles.
Or go to one of those racing schools and sign up for a few lessons, They can teach you about skidding and recovery and lots of other great useful stuff.
