“Each success brings with it the potential of failure and each failure brings with it the potential of success.”

Don’t ask ‘Why’, ask instead, ‘Why not’.

Let us not seek the Republican answer or the Democratic answer, but the right answer. Let us not seek to fix the blame for the past. Let us accept our own responsibility for the future.

The only reason to give a speech is to change the world.

Justice delayed is democracy denied.

Peace is a daily, a weekly, a monthly process, gradually changing opinions, slowly eroding old barriers, quietly building new structures.

The ignorance of one voter in a democracy impairs the security of all.

It is insane that two men, sitting on opposite sides of the world, should be able to decide to bring an end to civilization.

Those who do nothing are inviting shame as well as violence. Those who act boldly are recognizing right as well as reality.

Our most basic common link is that we all inhabit this planet. We all breathe the same air. We all cherish our children’s future. And we are all mortal.

We need people who can dream of things that never were.

It is an unfortunate fact that we can secure peace only by preparing for war.

Democracy may not be perfect, but at least I don’t have to build a wall to keep my people in.

Every accomplishment starts with the decision to try.

Peace need not be impracticable, and war need not be inevitable.

One person can make a difference, and everyone should try.

Great crises produce great men, and great deeds of courage.
