But there is a story published this week on Newsweek's website titled "General David Petraeus's Rules for Living," written by biographer Broadwell.
No. 5 is notable in light of the news about his extramarital affair. "We all will make mistakes. The key is to recognize them and admit them, to learn from them, and to take off the rear-view mirrors -- drive on and avoid making them again."
The departure of Petraeus will add another hole to Obama's leadership team, which is expected to lose some high-profile faces in the coming weeks and months. Secretary of State Hillary Clinton is among the cabinet members who have said they will not stay in the administration for a second term. A hole at CIA will add yet another position that requires Senate confirmation to that list.
National Intelligence Director James Clapper praised Petraeus, who turned 60 two days ago, for his years of service.
"Whether he was in uniform leading our nation's troops in Iraq and Afghanistan, or at CIA headquarters leading the effort to generate intelligence used to keep our nation safe, Dave inspired people who had the privilege of working with him," Clapper said in a statement. "I have spent more than five decades serving our country -- in uniform and out -- and of all the exceptional men and women I have worked with over the years, I can honestly say that Dave Petraeus stands out as one of our nation's great patriots."
