Be confident, not certain

Happiness is not a goal; it is a by-product.

It takes as much energy to wish as it does to plan.

The most unhappy people in the world are those who face the days without knowing what to do with their time. But if you have more projects than you have time for, you are not going to be an unhappy person. This is as much a question of having imagination and curiosity as it is of actually making plans.

I can not believe that war is the best solution. No one won the last war, and no one will win the next war.

I feel quite sure that the American people, if they have knowledge and leadership, can meet any crisis just as well as they met it over and over again in the past.

I never met Mahatma Gandhi, but, I think everyone felt they knew him even if they hadn't met him.
