So, I'm gonna throw down and get controversial for a sec: William Shakespeare was the greatest playwright and poet who ever spoke English, and I'd relish a comment-fight-to-the-death in the comments anyone who disagrees (not really, but I encourage the conversation).
To argue the man's merits feels redundant; the work speaks for itself. The Bard's plays are so influential that he's taught us how we understand storytelling and character development in the modern and post-modern world. His words have become so ubiquitous that I'd bet good money everyone reading this knows unique phrases from at least 4 of the 5 speeches below (also lots of movies take their titles from his phrases). I challenge any man considering himself an educated member of our society read these speeches and attempt committing them to memory. You'll find them helpful in more than a few settings.
Part of being a good man is about continually expanding your horizons and having a sense of the things you like and the things you don't. That's why we're kicking off a new Everyman's Guide to some of the things about which we think every man ought to have a knowledge and opinion. And we're starting out with the great American genre of Jazz.
