I was a Christian. I didn't want to have sex before marriage, I was a bit uptight and not very self-confident. I was a virgin until I was 26.
Presidents with strong nerves are decisive. They don't balk at unpopular decisions. They are willing to make people angry. Bush had strong nerves. Clinton, who passed up a chance to eliminate Osama bin Laden, did not. Obama is a people pleaser, a trait not normally associated with nerves of steel.
