These days I only string for myself or friends. I have as much enthusiasm for stringing rackets as I do for doing laundry or washing my car. It's nice to have a freshly strung racket, clean clothes, or clean car after you are done but the task itself isn't exactly enjoyable. After a long day at work at least it's something that doesn't require any brainpower.
I used to find stringing enjoyable when I got paid to do it. It was an easy way to make money after the sun went down and the courts were closed. Eat some dinner, lock up the pro shop, turn on the TV/radio, and string for a couple hours with no distractions. Decent volume at my club so it was a steady source of beer money.
