I worked in retail prior to working at the hospital as a CNA. I was on my feet less in retail than in the hospital; because in retail I got my lunch each and every day that I worked. In the hospital, I could flip a quarter and that would probably be a reliable means of me getting a lunch. I work 12 hour days as well as go to school. Makes for some long hours. Shadow a CNA at a local hospital and see what you think. I personally like being a CNA better than retail, but ONLY because it helps me figure out what I like in nursing and what I don't. But only you can deside! Best of luck to you!! Maggie.
