Live as if you were living already for the second time and as if you had acted the first time as wrongly as you are about to act now.

...every human beeing has the freedom to change at any instant.

One should not search for an abstract meaning of life. Everyone has his own specific vocation or mission in life to carry out a concrete assignment which demands fulfillment. Ultimately, man should not ask what the meaning of his life is, but rather he must recognize that it is he who is asked. In a word, each man is questioned by life; and he can only answer to life by answering for his own life.

... the words of Bismarck could be applied: "Life is like being at the dentist. You always think the worst is still to come, and yet it is over already."

...everything can be taken from a man but one thing: the last of the human freedoms - to choose one´s attitude in any given set of circumstances, to choose one´s own way.

[...]that human life, under any circumstances, never ceases to have a meaning, and that this infinite meaning of life includes suffering and dying, privation and death.

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 about it.

...people have enough to live by but nothing to live for; they have the means but no meaning.

The salvation of man is through love and in love.

From all this we may learn that there are two races of men in this world, but only these two- the "race" of the decent man and the "race" of the indecent man. Both are found everywhere; they penetrate into all groups of society.
