Apparently my grandpa was a very bright man. The story goes... He was often asked "where did you get your degree?" because he demonstrated intelligence fat above normal. His answer?
"I have a PhD from the school of hard knocks "
Grandpa learned from life, using common sense and experience as the teacher and curriculum. There is no better teacher.
Intelligence does not come from school... It comes from god. School at best can bring facts (which are discoverable outside just as well) and challenge you to think (which we should do always anywhere) and at worst will destroy your ability to reason, replacing that work blind acceptance of started facts based on source, not truth.
