Elie Wiesel said this quote

There's a long road of suffering ahead of you. But don't lose courage. You've already escaped the gravest danger: selection. So now, muster your strength, and don't lose heart. We shall all see the day of liberation. Have faith in life. Above all else, have faith. Drive out despair, and you will keep death away from yourselves. Hell is not for eternity. And now, a prayer - or rather, a piece of advice: let there be comradeship among you. We are all brothers, and we are all suffering the same fate. The same smoke floats over all our heads. Help one another. It is the only way to survive.
