“We are on the edge of a new era. It can be something completely positive for Lebanon, and it can be something completely dark for Lebanon. … That's why we are really at a turning point where anything can happen.”

Exploration of Space (1952)
1950s
Context: We stand now at the turning point between two eras. Behind us is a past to which we can never return … The coming of the rocket brought to an end a million years of isolation … the childhood of our race was over and history as we know it began.

letter to Koichi Mano (3 February 1966); published in Perfectly Reasonable Deviations from the Beaten Track: The Letters of Richard P. Feynman (2005), p. 198, 201
also quoted by Freeman Dyson in "Wise Man" http://www.nybooks.com/articles/18350, The New York Review of Books (20 October 2005)
Context: The worthwhile problems are the ones you can really solve or help solve, the ones you can really contribute something to. … No problem is too small or too trivial if we can really do something about it. You say you are a nameless man. You are not to your wife and to your child. You will not long remain so to your immediate colleagues if you can answer their simple questions when they come into your office. You are not nameless to me. Do not remain nameless to yourself — it is too sad a way to be. Know your place in the world and evaluate yourself fairly, not in terms of the naïve ideals of your own youth, nor in terms of what you erroneously imagine your teacher's ideals are.
