The leaders we revere and the businesses that last are generally not the result of a narrow pursuit of popularity or personal advancement, but of devotion to some bigger purpose. That's the hallmark of real success. The other trapping of success might be the by product of this larger mission, but it can't be the central thing.

You wouldn't know that if you talked to Human Rights Watch or Amnesty International or some of the international activist organizations. Certainly you wouldn't know that if you were talking to some of the writers who criticize our drone policy. But I've actually told my staff it's probably good that they stay critical of this policy, even though I think right now we're doing the best that we can in a dangerous world with terrorists who would gladly blow up a school bus full of American kids if they could.

I can be much more sarcastic and, I think, sometimes withering in my assessments of things than I allow to show in my public life.

It's no wonder that America's engagement in the region has strong, sustained, bipartisan support. So I'll be handing my successor a strong foundation - including closer ties with Singapore - on which to continue building, and I'm optimistic that will happen.

The Muslim call to prayer is one of the prettiest sounds on Earth at sunset.
