Education consists mainly in what we have unlearned

The first half of my life I went to school, the second half of my life I got an education.

Education: the path from cocky ignorance to miserable uncertainty.

There is nothing training cannot do. Nothing is above its reach. It can turn bad morals to good; it can destroy bad principles and recreate good ones; it can lift men to angelship. -Mark Twain.

I've never let my school interfere with my education.

Don't let schooling interfere with your education.
