Yes one would do better to keep educating one self. Brian Tracy would talk about his, University On Wheels. That is using audio books as you drive. Very good if you drive a lot. I always try to buy the used books. I am frugal that way. Also it is the way of, The Millionaire Next Door another book to add to the library. I found a really good book called, If You Can Talk You Can Write for only $0.15 plus shipping and handling on Amazon. Great blog @stackin.
