The NYTimes reported that Barack Obama met Tory leader David Cameron during his visit to England last week. Cameron asked Obama if he will be taking any time off for a vacation this summer:
Mr. Cameron: Do you have a break at all?
Mr. Obama: I have not. I am going to take a week in August. But I agree with you that somebody, somebody who had worked in the White House who — not Clinton himself, but somebody who had been close to the process — said that should we be successful, that actually the most important thing you need to do is to have big chunks of time during the day when all you’re doing is thinking.

Mr. Obama: And, well, and you start making mistakes or you lose the big picture.

It's about having more time to think. And to keep an eye on the big picture.
