Jobs I've Dreamed of versus Jobs I've Had

I'd say I've done fairly well in terms of actually working in fields in which I have an interest, as can probably be surmised by the handy timeline below.
The timeline shows my main dream job at top, my main real jobs at bottom. This isn't exhaustive, though, because I have had part-time second jobs, and there have been other jobs I've dreamed of having. For example, at various times, I've thought how need it would be to be a screenwriter, an amusement park ride designer, a fruit farmer, a comedian, a radio deejay, a publisher, and a designer or compositor. In real life, I've done a little deejaying (for pay--it was not something, in the end, that I enjoyed), and I've done some design and composition and screenwriting just for fun.

But I'm blessed that the job I really desired from about my teen years on became the one that I have. I often ponder what I would do instead were I to have to choose another career, and the fact is I don't know.
