There are a lot of jobs I would like to try for one day. The one I’m thinking of, however, is mayor of a small town. I think I could handle that job for about a day. I couldn’t do much damage in one day, I figure, even if I’m bad at it. I know there would be a lot of administrative decisions I would need to make, many routine. It would not be an exciting time. I’d still like to do it, just to say I did.

There are other jobs I would like to do for a day. Cat rescue. Journalist. Disaster case manager. Extra in a movie.
There are a lot of jobs I wouldn’t like to do because I don’t have the physical prowess or the mental know-how. I don’t want to be a stunt double, or a doctor, or a professional makeup artist. (I would like to try professional moulage artist if there’s on-job training, but making someone look beautiful is too hard.) Nor would I want to be a fashion designer, an actor, or an engineer.
Professional author? I would love that, because it would mean that I’ve been picked up by a publisher. I could do that for more than one day!
