President Bush says he hopes his memoir gives readers a better understanding of who he is and the decisions he made.
"When it was over, I knew I'd given my heart and soul, I'd poured everything I had into the job and was grateful for the opportunity to serve," he says.
President Bush says the writing process was easy, even fun. "I know full well it's going to come as a shock to some people. A lot of people didn't think I could read, much less write," he jokes.
