Some may think that a teacher has an easy job, but I tend to disagree.  Teachers must have a load of patience because they will definitely need it.  My daughter wants to teach music and I told her that she needs to make sure that she will like it before she completes her degree.  She does not have a lot of patience and I really worry about it.  I told her to start by offering free electric guitar lessons to the children in our neighborhood and this would give her some idea about what teaching would be like.  She loves the idea and already has a few students signed up.
