Endowed with a stable root structure of learning ability, J.T. is mostly self-taught. Remaining credit can be attributed to all the people and external affectuations, including but not limited to the public education system which -- beyond middle school -- mostly reinforced his choice to continue to self teach by showing him how not to teach.
J.T. has helped others learn along the way, and continues to educate others via an increasing reservoir of knowledge and wisdom, even when not paid for the service, happily. When taking the Long Ridge Writer's Group course, he detected a couple typos, marking them for whomever would grade the test, and filled out the "describe how to perform a task" section with a "how to" about teaching yourself to perform a task.
Years later, when attempting an online college course, J.T. assisted the professor in answering questions from other students, essentially acting as a teacher-aid for an English class.
