Your words here reflect what Booker T. Washington said with, "Cast down your bucket where you are." Very good, metmom. I completely agree.

There's a difference between knowledge and intelligence. A high quality education can lead to a great deal of knowledge, but a low level of intelligence.
Conversely, a rough life without decent formal schooling can render one short on knowledge, but long on intelligence.
I would argue that true intelligence leads to strong morals, and a life of integrity.
