In this last collection of clips, see at the end, advice Heschel gave to youth:
I would say to young people a number of things, and I have only one minute. I would say let them remember that there is a meaning beyond absurdity. Let them be sure that every little deed counts, that every word has power, and that we can do, everyone, our share to redeem the world, in spite of all absurdities, and all the frustrations, and all the disappointment. And above all, remember that the meaning of life is to build life as if it were a work of art. You're not a machine. When you're young, start working on this great work of art called your own existence.
