The difference between procrastination and laziness is that procrastination at least achieves something, but it is the wrong thing at the time. Laziness is just sitting back and saying "I'll do it later", while procrastination is saying "First I'll do some laundry, then wash the dishes, then clean my room...".

PPS - But obviously choosing to do your work is better by far.
