You dont know how wrong you are!! Some people find getting up at the crack of noon hard but not me! Uni life is good life.
One piece of advice that I've found thru experience is workout if the course is right for you early. Many of my friends went into courses because they wanted to have a particular title, they knew there was money at the end of it, or the course name sounded good. Eg a mates sister wanted to do Aviation coz "It sounds fun". Her problem was she hated physics and maths. She then wondered why she couldnt find the motivation to do the work and hence kept failing. Another friend started 2 uni degrees, a tafe course and dropped out of all 3. He is now doing Mech Eng and averaging 92% and aiming for 1st Class honours. Something to think about.
Anyways, Have Fun!
