It is here that we encounter the central theme of existentialism: to live is to suffer, to survive is to find meaning in the suffering.

Don't aim at success — the more you aim at it and make it a target, the more you are going to miss it. For success, like happiness, cannot be pursued; it must ensue, and it only does so as the unintended side-effect of one's personal dedication to a cause greater than oneself or as the by-product of one's surrender to a person other than oneself. Happiness must happen, and the same holds for success: you have to let it happen by not caring about it. I want you to listen to what your conscience commands you to do and go on to carry it out to the best of your knowledge. Then you will live to see that in the long run — in the long run, I say — success will follow you precisely because you had forgotten to think of it.

These tasks, and therefore the meaning of life, differ from man to man, and from moment to moment. Thus it is impossible to define the meaning in life in a general way.

Everywhere man is confronted with fate , with a chance of achieving something through his own suffering.
