The most important thing you can learn, is how to learn. One of the things that most upsets me is when I hear someone say they can't do something "because no one ever taught me how". It's not your teachers/parents job to teach you how to do everything under the sun.

Ignorance is nigh-inexcusable in today's society, with so many sources of information at our fingertips. That's where the "poorly educated" part comes in for me - folks who don't know how to search for and evaluate information.
