But if the life will not be easy, it will be rich and satisfying. For every young American who participates in the Peace Corps-who works in a foreign land-will know that he or she is sharing in the great common task of bringing to man that decent way of life which is the foundation of freedom and a condition of peace.

We in this country, in this generation, are, by destiny rather than choice, the watchmen on the walls of world freedom.

As every past generation has had to disenthrall itself from an inheritance of truisms and stereotypes, so in our own time we must move on from the reassuring repetition of stale phrases to a new, difficult, but essential confrontation with reality. For the great enemy of truth is very often not the lie-deliberate, contrived and dishonest-but the myth-persistent, persuasive and unrealistic. Mythology distracts us everywhere.

Our growing softness, our increasing lack of physical fitness, is a menace to our security.

Effort and courage are not enough without purpose and direction.

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

A revolution is coming – a revolution which will be peaceful if we are wise enough; compassionate if we care enough; successful if we are fortunate enough – but a revolution which is coming whether we will it or not. We can affect its character; we cannot alter its inevitability.
