“Almost all of our sorrows spring out of our relations with other people. There is no more mistaken path to happiness than worldliness.”

“What a man is contributes much more to his happiness than what he has or how he is regarded by others.”

“Other people's heads are too wretched a place for true happiness to have its seat.”

“What disturbs and depresses young people is the hunt for happiness on the firm assumption that it must be met with in life. From this arises constantly deluded hope and so also dissatisfaction. Deceptive images of a vague happiness hover before us in our dreams, and we search in vain for their original. Much would have been gained if, through timely advice and instruction, young people could have had eradicated from their minds the erroneous notion that the world has a great deal to offer them.”

“There is one thing that, more than any other, throws people absolutely off their balance — the thought that you are dependent upon them. This is sure to produce an insolent and domineering manner towards you. There are some people, indeed, who become rude if you enter into any kind of relation with them; for instance, if you have occasion to converse with them frequently upon confidential matters, they soon come to fancy that they can take liberties with you, and so they try and transgress the laws of politeness. This is why there are so few with whom you care to become more intimate, and why you should avoid familiarity with vulgar people. If a man comes to think that I am more dependent upon him than he is upon me, he at once feels as though I had stolen something from him; and his endeavor will be to have his vengeance and get it back. The only way to attain superiority in dealing with men, is to let it be seen that you are independent of them.”

“What light is to the outer physical world intellect is to the inner world of consciousness. For intellect is related to the will, and thus also to the organism which is nothing other than will regarded objectively, in the approximate same way as light is to a combustible body and the oxygen in combination with which it ignites.”

“The vanity of existence is revealed in the whole form existence assumes: in the infiniteness of time and space contrasted with the finiteness of the individual in both; in the fleeting present as the sole form in which actuality exists; in the contingency and relativity of all things; in continual becoming without being; in continual desire without satisfaction; in the continual frustration of striving of which life consists. . . Time is that by virtue of which everything becomes nothingness in our hands and loses all real value.”
