Former US president George W. Bush, who once famously called himself "The Decider," is writing a book about decisions. "I want people to understand the environment in which I was making decisions. I want people to get a sense of how decisions were made and I want people to understand the options that were placed before me," Bush said during a brief telephone interview Wednesday with The Associated Press from his office in Dallas. Bush's book, tentatively (not decisively) called "Decision Points," is scheduled for a 2010 release by Crown, an imprint of the Crown Publishing Group. It is unusual in a couple of ways. Instead of telling his life story, Bush will concentrate on about a dozen personal and presidential choices, from giving up drinking to picking Dick Cheney as his vice president to sending troops to Iraq. He will also write about his relationship with family members, including his father, former US president George H.W. Bush, his religious faith and his highly criticized response to Hurricane Katrina.
