John Adams. It appears that young John Adams ran into a lackluster "churl" of a teacher early in his educational life and told his dad he wanted to be a farmer. Dad decided to switch schools and Adams came into contact with the aforementioned Joseph Marsh. The change was immediate and powerful.
John made a dramatic turn and began studying in earnest.
What a wonderul illustration of the power of a teacher. In this case we observe the power of a poor teacher to nearly kill the spirit of an obviously capable young student as well as the power of an outstanding teacher to re-ignite interest and enthusiasm toward learning. A salute to all the teachers who have paved the way for great achievements of their students both past, present, and future!
