Teaching an old dog new tricks?

How many times do you have to teach someone how to do something before they will know how to do it themselves? One of my co-workers keeps asking me the same questions about how to edit a web page. I already gave her a full hands-on tutorial. Yet each time, I have to explain using a step-by-step process and she won't try anything on her own because she's afraid of messing things up. Copying and pasting folders isn't rocket science. After I explain the basics to someone, I expect that person to run with it. I don't like wet-nursing sandbaggers.
