Who can learn to do this stuff?

The first time you turn on your GIS, it will look very foreign, but with a day or 2 of training, most people can learn what they need to know to get a good start. No special talent or education is needed. Just be willing take the time to learn. Also, keep in mind that even if you can't remember how to do something, the fact that the software is capable of doing something is the first step in the learning process.
