Resilience

There is no way to really prepare a teacher for the stresses of teaching. They can be warned in advanced, given tips of how to deal with certain situations, and be given support resources, but in the end each teacher is going to have to experience it for themselves and find their own ways of de-stressing. The only way to keep 50% of teacher from changing professions early on is to give them as many skills as possible before hand, get them into classrooms while still in college, and give them a support system for when they have a classroom of their own.
