6. Not learning good time management!
If you were never good at managing your time, then you had better start doing it now that you are attending college. If not, then you are in for a rude awakening because your schedule in school is going to be hectic at times and hard to handle without a good plan of action. You also have to fit in time for study, eating, exercising, relaxing and sleeping! You can’t just charge into things and expect it all to work out on its own. Get a time management plan and use it!
