"My dad really loves reading about great leaders during the warring periods of Japan, a hobby that's probably influenced by the fact that he shares Toyotomi Hideyoshi's name. Much of his philosophy on managing businesses comes from talking about them. ...Did you know? Takeda Shingen, who was feared as the leader of the strongest cavalry corps in the warring periods, started out with his troops in complete disarray...and didn't have the kind of strong leadership necessary to utilize them well."
