On my feet all day,
and on my back most of the night, under the wife’s car finishing the muffler flange gasket job I started last night.
I always have a bucket of crap going on. As often as not I end my day with my feet feeling as if I’ve been subjected to an extended bastinado session, my knees and back screaming, shoulders aching, hands sore, and often bleeding from all over the damned place.
The more I do it the better and happier I feel, not because I enjoy the pain, because I don’t.
I feel good because I accomplish things, and I sleep the deep and restful sleep of the laborer. My head hits the pillow feeling sorry for the folks who didn’t work that hard today, because they will wake up feeling the same way they went to bed.

Good point, actually being able to ‘see’ the output of your labors is worth it!
NFO: your gig is “Make sure nobody dies!’ Thats plenty hard work.
