In 2004 I took the tests to be a letter carrier (including the "memory for addresses" section and an inductive reasoning section on sequences) and was almost offered jobs twice -- once as a rural carrier (too hard on car) and then on foot, which would have been a very "physical" job, I was told. (And you have to be accurate, starting with "casing" the mail.) The inability to get my medical records from Minnesota (HIPAA makes it very hard) was all that nixed this. TIP: When you move to another city, make sure you check on how you will get any health care records later; some are not kept for more than four years, and some employers might need to see records of past surgeries.
And in Minneapolis, in 2003, I actually looked at becoming a cabbie. You rent the cab for $400 a week and are "self-employed". Sounds like you have to learn to drive aggressively. You need a physical.
I did work for about three years as a substitute teacher, which I have written about elsewhere a lot. That was probably, in the end, the most interesting of the interim jobs.
I think I have discussed the approaches made to me about becoming a life insurance agent or tax advisor. Sure, I would "love" to peddle financial and tax schemes to "families". Oh, yes, new agents need to generate leads and get a "fast start". Actually, my resistance to these "opportunities" does deserve further explanation.
