One of mine, the one that life's happenings (i.e., work) tend to interfere with is the same as Debbie's passion: Writing.

I used to do it as a vocation, but, later changed professions.

My degree, like hers, is in the relevant field. I've had quite a number of (non fiction) pieces published and do have a couple book ideas sitting in my head. I've run the titles and gist by my doctors, and ... they laughed. . That's always a good sign, especially since the chosen genre is humor. Only drawback is getting one of my docs. to write the fwd.
