Often, we are told to develop a big project during the classes since day one. For that kind of projects, you should reserve time each day (at most 30 minutes). By doing so, you will complete that project earlier than expected, you won't be worrying about deadlines and you will finish it before you notice it even started.

Keep a list with all the tasks you have to do, and rewrite that list with different colors, writing with the same tasks that have something in common, not about the subject but about the matter....
