Leadership Lessons: Warren Buffett Warren Buffett is the most successful investor in history. From his humble beginnings in Depression-torn Nebraska, he became one of the world's wealthiest men before he started giving away his billions. But his wealth and power are balanced by self-deprecating wit, a modest lifestyle, and a well-earned reputation for honesty. In truth, Buffett is far more complex than he appears, and he owes his success to hard work and his ability to spot value that others overlook. As this short-form book by bestselling author and consultant Will Peters shows, Buffett's insights, principles, and precepts hold lessons from which all investors can profit.
