Francois Hollande

In my own situation, I cannot show anything... And I believe that everybody now understands that, president or not president, one is entitled to have a private life. But of course when one is president, this creates duties and obligations.

France isn't just any country in Europe, and its president is not an ordinary leader in the world. Sometimes directing or leading the way is not enough, he has to initiate policies, as Nicolas Sarkozy was able to demonstrate during his term.

And I think that still is true of this business - which is basically research and development - that you probably spend more time in planning and training and designing for things to go wrong, and how you cope with them, than you do for things to go right.
