What Qualities Make Good Technicians?

rderek asks: "I am an instructor at an educational, and my focus is on computer technicians (not sys-admins). The course that we run is very demanding, and produces (we think) very good techs. We are allways in the process of adjusting our cirriculum to remain current, but it may be time to adjust our teaching process. What we want is not simply to create people who know how a computer works, but who also have the attitude and mindset of good technicians. I would like to know what each of you consider to be the qualities necessary for a person to be a good tech."
