What makes a good teacher?

There are many definitions of what it means to be considered a "good teacher"... Some say a good teacher is someone who makes learning fun, or someone who connects with students and keeps their attention. I really liked the way authors Morgan and Saxton described what their opinion was of what it meant to be a "good teacher" in their book Asking Better Questions. They said "a good teacher capitalizes on the innate feeling by attracting, maintaining, and satisfying the attention of learners while giving them something worthwhile to think about."
