“Spend 80 percent of your time on books and 20 percent on articles and newspapers. And by books, I don’t mean just any book. I mean hardcovers. A paperback is made to be read. A hardcover is made to be studied. There’s a huge difference.”

“The paperback is very interesting but I find it will never replace the hardcover book -- it makes a very poor doorstop.”

“If you give only 80 percent leadership, your dog will give you 80 percent following. And the other 20 percent of the time he will run the show. If you give your dog any opportunity for him to lead you, he will take it.”

“Economists often talk about the 80/20 Principle, which is the idea that in any situation roughly 80 percent of the “work” will be done by 20 percent of the participants. In most societies, 20 percent of criminals commit 80 percent of crimes. Twenty percent of motorists cause 80 percent of all accidents. Twenty percent of beer drinkers drink 80 percent of all beer. When it comes to epidemics, though, this disproportionality becomes even more extreme: a tiny percentage of people do the majority of the work.”

“If you read one book a week, starting at the age of 5, and live to be 80, you will have read a grand total of 3,900 books, a little over one-tenth of 1 percent of the books currently in print.”

“If I finish a book a week, I will read only a few thousand books in my lifetime, about a tenth of a percent of the contents of the greatest libraries of our time. The trick is to know which books to read.”
