A good teacher of the Craft should be patient and flexible. Not everyone learns at the same pace or in the same way. There may be some students who can pick up on an idea or concept very quickly, there are some that need more time and one on one tutoring, and then there are some who may never understand. A good teacher knows that sometimes you have to slow the pace down for those who don't quite understand yet keep it interesting enough for those who already do. A good teacher of the Craft should be tolerant.
Paganism is a very diverse path.
Those past experiences shape the way each student thinks about Paganism, magick, religion, and people in general. Being able to do magick is a very powerful thing. Taking that to the teaching level means that you are directly responsible for someone else's magical training. It can be real easy to think of yourself as greater than you are because you can do magick and someone else can not. You are, however, still a flesh and blood person and are teaching a flesh and blood person.
