Victor Frankl on Meaning in SufferingMan's Search for Meaning (Washington Square Press: 1963).
Not only creativeness and enjoyment are meaningful. If there is a meaning in life at all, then there must be a meaning in suffering. Suffering is an ineradicable part of life, even as fate and death. Without suffering and death human life cannot be complete. ¶ The way in which a man accepts his fate and all the suffering it entails, the way in which he takes up his cross, gives him ample opportunity — even under the most difficult circumstances — to add a deeper meaning to his life. It may remain brave, dignified and unselfish. Or in the bitter fight for self-preservation he may forget his human dignity and become no more than an animal. Here lies the chance for a man either to make use of or to forgo the opportunities of attaining the moral values that a difficult situation may afford him. And this decides whether he is worthy of his suffering or not.
