I wish we had an eye-roll symbol I could click for some of these stories!
I also like structure. I'm not super-enthused about my job, but it's a good job for me--it fits my lifestyle, as Amara says. I tend to be very structured about my hobbies, too--I have plans and goals and lists for them. It makes me feel very satisfied. So if I ever had the chance to live comfortably job-free, I know I would set up a new schedule, where I worked on each hobby a certain amount each day, or accomplished certain goals with them. It would be the same sort of structure work gives me now, but I would be getting more done on things I enjoy.
Of course there are other reasons to work. And, I think there must be jobs that don't have so much structure, that appeal to people who like a little more freedom. But, in pretty much every job you have to be reliable--reach the goals that are set, do what you said you would do, produce work to a certain quality. In job education programs, like for ex-cons, they don't emphasize the skills they need for a particular job, like electrician stuff--they emphasize the need to show up on time, get your work done well, communicate when you won't be there, etc.. The technical skills, you can learn on the job. Employers don't want someone who isn't reliable, though, no matter how brilliant they may be in some other way.
