>"Lincoln's War Cabinet by Hendrick Burton - learn to surround yourself with ideas you don't necessarily agree with and be influenced by the most unlikely minds"

"Team of Rivals" by Doris Kearns Goodwin explores the same topic, specifically how Lincoln made up his cabinet from talented rivals.

Apparently Obama referred to this book (reference http://blogs.abcnews.com/politicalpunch/2008/05/obama-propos...) which made me curious enough to buy it. It is a great read and a fascinating study in leadership.
