For the first time ever, I had a plumbing job that went by the book. The "man's bathroom" toilet was in need of repair. (that's a 7hp, 2-stage, 80gal air compressor in the bathroom too.) The decades old flapper had rotted away and the flush valve never quite turned off. I bought a tank repair kit, and then ignored it for weeks. I finally worked up the nerve to install it today. Amazingly the water shutoff actually worked, no fasteners were stuck and all the old hardware was easily removed. I installed the new components, screwed everything together and turned the water back on... and it just worked. Total time, about 20 minutes. Compare this with the upstairs toilet... I was just replacing the valve, but the standpipe cracked. So I had to get a new one. Then the old one wouldn't come off and I had to saw it off. Then the shutoff valve started leaking. I replaced it, only to find that the elbow behind the wall was corroded and leaking into the kitchen ceiling... and so on. That job took me about 15 hours over 3 days. I still hate plumbing.
