A good teacher will be able to explain something many different
  ways so that the student will understand while also listening to
  see if they, themselves, may be wrong and be willing to accept
  correction. I almost became a teacher and have considered it a
  lot in life. There's not much schooling required for it. I was
  expecting some heavy duty courses in communication, concept
  formation, concept explanation, teaching methodologies... but
  the classes were like "Grade 13", as if I was taking a
  mysterious hidden course I didn't know about that covered an
  overview of 12 years of schooling but it was no different than
  what I learned in school. It wasn't any deeper. Maybe there
  would have been more to it had I finished. Also, I can't extract
  myself from my history completely: I never finished college.
  Would I know more now if I had finished college + the Internet,
  vs finished college + no Internet vs didn't finish college + the
  Internet (what happened) vs didn't finish college + no Internet
  ? How can I compare when I only took one of those routes?
