The Snowball: Warren Buffett and the Business of Life
by Alice Schroeder, 2008

Long read (~850 dense pages), but very rewarding. Very well written. Gives insights into Buffett’s thought processes. He was/is supremely focused on business issues, sometimes to the detriment of other aspects of his life. But his honesty, work ethic, and teaching mentality took him a long way in life, obviously. Strongly recommended.
