Efficacy

Self-awareness, confidence, persistence, work ethic, and belief in one's ability are all super important traits which all teachers should try to acquire.  I think it's kind of hard to lump all of these traits into one group, so I'll split them up.  Clearly, I have excellent problem-solving skills.  Here goes.

Self-awareness is an important trait to have as a human being in general, but it's especially important to human beings who happen to be teachers.  It's always good to know how you're perceived.  If students aren't responding to you because you're super lame, it's good to be aware of your lame-ness and do something to change it so they can relate to you better.

Confidence and belief in one's ability kind of go hand in hand.  They are both good skills to have, because people tend to listen to people who seem to know what they're talking about.  If students don't think that a teacher knows their stuff, they won't think that they have to know the material, either.

Persistence and work ethic good qualities for teachers to have, as well.  Students are not always going to have an easy time learning material, or they may not want to learn the material at all.  Teachers need to be persistent so their students will learn what they need to learn.

I think that all of these attributes are either learned or inborn. Belief in one's ability sometimes comes with time and experience.  However, work ethic is kind of something people are born with, although I guess it could be learned.
