For success, like happiness, cannot be pursued; it must ensue, and it only does so as the unintended side-effect of one's dedication to a cause greater than oneself or as the by-product of one's surrender to a person other than oneself.
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.
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 sufferings or not.
He who has a why to live can bear almost any how.
As far as we can discern, the sole purpose of human existence is to kindle a light in the darkness of mere being.
