Maybe all of the above
In high school and for several years afterwards I was a professional photographer of show horses. Enjoyed it, but it was grueling work. I also spent some time selling cameras and then working as an industrial photographer for Fairchild Space and Defense (boring taking pictures of circuit boards). I then made a career change and spent the next 30 years working in the computer field (programming, analyst, sales, training and consulting). The rewards were good and let me live the lifestyle we enjoyed, but that all ended on Oct. 24th, 2003. Just after we'd seen the last commercial flight of the BA
Concorde I got news that my dept. was eliminated and, along with it, my job. No one is anxious to hire someone with gray in their hair and beard, so I've been out of work ever since.
That is, unless you count photography as my work. I'm currently reevaluating my wants and desires and may just make this photography thing my profession once more. It's a lot more fun than a lot of other jobs and the freedom of being your own boss can't be beat.
