I learned a great deal from this online book: Barbara Sher's Wishcraft

When I was in a boring, going nowhere job out of school, I used the time to look around me and see that there were a whole lot of jobs around me I could look at and imagine myself in to see if they fit. All companies have lots of different types of tasks, administrative, financial, transportation, sales, corporate, customer service and just wandering around the store (I worked at Sears & Roebuck :-) there were lots of different departments with different kinds of products, all with their own needs (furniture department, appliances, clothing, automotive). At one point I was discussing moving to the security department but a car fell off a lift in the automotive garage as I was being interviewed by the security department head and he had to leave in a hurry

Look around you and at least move sideways into a field or product that interests you. Clerical, sales, or customer service background can work just about anywhere. Once you are more closely aligned, then you can look at how to move up, whether you need to save for additional schooling or just put in your time and work hard for a few years.
