I was never much of a lazy person, but I shall try to help.
I always make lists of things that I need to do everyday. Whether it is do homework, go shopping for food, or various other tasks. I make myself follow the lists.
I also have a schedule of things at all times. I'm all about time management. Set certain times that you'll do things. That really helps. As an example I have a set amount of time that I spend on homework that way then I get it done and can relax the rest of the day if I don't have something to study for.
Wake up everyday at the exact same time so you don't sleep in and make it a lazy day.
I'm not saying that taking a day to relax is bad. I just wouldn't make it often.
