My top two
choices are:
1. Independently wealthy. No explanation needed.
2. Guitarist in a rock band. I love music, I'd love the attention and money, and I'd also love the lifestyle (I'm a night owl).
Or did you mean things that I could realistically do?
I did customer support for a software company for a year or so and I loved loved loved
that job. I loved solving problems for people and I loved how task-oriented it was. I picked up the phone, answered the question, and then moved on the next call. Every day I left work with a sense of having accomplished something. I really missed it when I moved on.
I have to say that my current job (I run a professional association) has a lot of what I'd want in my perfect job. I get to think about things that are very interesting to me; I do some writing; I respond to inquiries from our members; and I do some public speaking. It's also a pretty high profile position, which I enjoy. Plus I work from home full time and have a very flexible schedule. Heck, we even have our own discussion forum and when I'm in there posting answers to questions, I can count it as working. Unfortunately, there's also a lot of stress that goes along with running an organization.
Sometimes I fantasize about opening a restaurant (that serves healthy entrees in reasonable portions). I also sometimes think it would be nice to work outside, maybe at a nature reserve (but I wouldn't want to do any heavy lifting). And there are definitely days when I fantasize about being a receptionist (there's no work to take home and no waking up in the middle of the night thinking of things I forgot to do).
