I like learning new things and was getting a bit bored. So much work out there so why not play around a bit, get paid and learn a few new things.
This! This! This!
I've been in this scenario and even wrote something about it long ago. I'm a firm believer in "stacking skills" and some of them are harder to learn from home/on your own OR will take much longer to learn VS working somewhere (close by of course, within walk/bike distance..).
For example, I'd love to be a bartender, not for income, but to learn the role and interact with folks (though I'm an introvert...).
I'd love to operate heavy equipment, yes, I could rent a small backhoe from HD but I'd rather get my mitts on something substantial, graders/cranes/you name it... Not many chances to do that outside of a "job".
I'd love to clean windows at the tallest buildings in my area, being outside, up in the air, it would be worth it (very flat here, 2 hours to nearest chance to do any climbing/repelling).
I don't see a future where this desire (to build more skills and maybe travel, on someone else's dime) goes away, I'm working on being happy just being ME right HERE and NOW, BUT, the internal drive to continue to learn/grow/expand seems to be innate and very hard to "shush", so I continue to seek opportunities to try new things, and if I earn an income/get benefits.... ok...
