Washington, Mar 19 : Former US President George W. Bush has written about 30,000 words of his memoir tentatively titled "Decision Points" that will cover everything from how he found faith, to how he quit drinking and chose Karl Rove and Dick Cheney for their respective jobs.

A contract with Crown, an imprint of Random House, is to be announced on Thursday. The same publisher issued both of President Obama's books, Politico reports.

The first chapter will be about the former president's early life leading up to his decision to run for president, and the final chapter will be about the financial crisis.

Aides say Bush is taking a disciplined approach, working two to three hours each morning, writing 1,000 to 1,500 words a day.

He has been typing on computers at his ranch in Crawford, his home in Dallas and his office in Dallas, and on a laptop he carries on planes and the ride between the ranch and the city.

On a trip this week to Calgary, Canada, for his first public speech since leaving office, he edited print outs.

"He wanted to do something different - less conventional and chronological, not an exhaustive history," an aide said.

"He thinks it'll be more interesting for people to read now, and a more important contribution to history, if he can focus on the big stuff. And he wants to write a book that people will read, not just buy."

Robert Barnett, the Washington lawyer who negotiated the deal, said the former President began writing two days after he left Washington, and spends two to three hours working on the book each morning on his computer at his Dallas office.

The book is due to be out in the fall of 2010, after Laura Bush has published her book earlier that year. The aide said it would be very different from Bush's first book, "A Charge to Keep". (ANI)
