Brett Dickerson over at Life At The Intersections has hit the nail on the head again. While many people do have an innate ability to teach, ultimately, teachers must develop their skills over time. In order to do this:

And they develop faster and better when they are in a well-organized, affirmative, financially supported process. [Italicized emphasis is mine.]
