In fact, it goes deeper than that. My inertia is in my marrow. See, an extension wouldn't do me any good. If time stopped for everyone but me, and I was suddenly magically gifted with a two-week extension, I'd probably take a week or ten days off, and then look over my shoulder, see the boot descending, and get busy. I don't look far ahead. It may have something to do with my short-sightedness. It may be philosophical: like Mr Wright says, Hard work pays off sometime in the future; laziness pays off now.
I wonder if I can get a marrow transplant? Get rid of my crippling inertia, replace it with good healthy ertia. Problem might be to find a donor.
