Go to bed smarter than when you woke up.

~ Charles T. Munger

In my whole life, I have known no wise people (over a broad subject matter area) who didn't read all the time -- none, zero. You'd be amazed at how much Warren reads--and at how much I read. My children laugh at me. They think I'm a book with a couple of legs sticking out.
