“It is in the nature of a leader’s work that he should be a realist and should recognize the need for action, even when the outcome cannot be foreseen, but also that he should be idealist and in the broadest sense pursue goals some of which can only be attained in a succeeding generation of leaders. Many leaders when they reach the apex of their powers have not long to go, and they press onward by paths the ends of which they will not themselves reach. In business, in education, in government, in religion, again and again, I see men who, I am sure, are dominated by this motive, though unexpressed, and by some queer twist of our present attitudes often disavowed. Yet, ‘Old men [and old women] plant trees’… to shape the present for the future by the surplus of thought and purpose which we now can muster seems the very expression of the idealism which underlies such social coherence as we presently achieve, and without this idealism we see no worthy meaning in our lives, our institutions, or our culture.”

1963, President John F. Kennedy's last formal speech and public words
Context: I think the United States should be a leader. A country as rich and powerful as this which bears so many burdens and responsibilities, which has so many opportunities, should be second to none. And in December, while I do not regard our mastery of space as anywhere near complete, while I recognize that there are still areas where we are behind — at least in one area, the size of the booster — this year I hope the United States will be ahead. And I am for it. We have a long way to go. Many weeks and months and years of long, tedious work lie ahead. There will be setbacks and frustrations and disappointments. There will be, as there always are, pressures in this country to do less in this area as in so many others, and temptations to do something else that is perhaps easier. But this research here must go on. This space effort must go on. The conquest of space must and will go ahead. That much we know. That much we can say with confidence and conviction.

L'homme croit souvent se conduire lorsqu'il est conduit; et pendant que par son esprit il tend à un but, son coeur l'entraîne insensiblement à un autre.
