I think honestly the best way to get started if your really unsure, build up your resume by working at jobs you hate, including, resturants, fast food, convenience stores like family dollar, dollar tree, etc. LOL we all have something you wouldn't mind doing to start a resume, I know they arent good enough but its a start. Good luck trying to get a job in an office.
I believe jobs like customer service for a car dealership is a good job on your resume. Out of the ordinary jobs are what i believe employers like to see.
