What is lazy?

Im not lazy. I tell myself that. I mean, I work everyday...okay, almost every day. Still, as soon as I sit down, as soon as I refuse to do something that I should be doing, I feel lazy. How can people work and move around constantly? Is my drive really that much lower than everyone else's? So, what is lazy? Is it okay to be lazy and if so, do I need to schedule it? If I schedule it, is it lazy? I think I have the "I don't want to" blues. I want to sit and eat goldfish crackers. I don't want to write articles, grade papers, water the lawn, walk the dog, furminate the cat, eat healthy, workout, make syllabi, or be helpful. That is lazy, right?
