When you procrastinate on mopping the floor or mowing the lawn, you're making a choice to live with dirtier floors or longer grass in exchange for more time to spend on other things. Some of that work actually goes away forever when you procrastinate. It's not like you mow the grass twice to make up for missing a week!
Perhaps the difficult emotion that 'lazy' people are avoiding is admitting to themselves that they're ok making that trade-off.
