But I do feel that there are some dispositions that can't be taught. For example, if you are extremely intelligent but don't particularly like children - you shouldn't be a teacher, no ifs ands or buts. Teaching is not the profession for you.
I also think you can learn a lot from watching other great teachers. Witnessing the skill in someone else makes it easier to understand and also apply to your own life. Personally, I am willing to try new ideas, and also utilize ideas from other teachers in order to become a better teacher myself.
