There is laziness and there is procrastination. Leaving that soda bottle on the floor is procrastinating picking it up; I'll still have to do it later. Having a small box to fill with soda bottles that I dump once every few weeks is laziness. Not making my bed when I'll have guest over or I need to make it before going to bed is procrastination. Not making it because there is no reason for it to be made before I get back into it is laziness (of course there are suprise visitors and such, but that is just cases where hueristical optimizations are imperfect).
