I Would Like To Change My Career. Please Help!?

I was wondering if any of you had any ideas on what I could do for a new career. My husband lost his job again and I want to take over with making the money, so I do not have to worry so much. Right now I work in the medical field and do not like it at all. The only career that I can think of doing would be over the solo road truck driver. Thanks for your help.
