If one experiences unrequited love, it helps to read Lucretius.

The value of philosophy is not so much that different than the value we have for music. The value of philosophy lies in the aesthetic effect it can have on the life of man. It makes life beautiful despite its insignificance.

Our relationships with other people lose significance in time. With each goodbye we expect less and less from each hello. This does not mean, of course, that we should stop from saying hello.

Regarding our dealings with other people: Expect nothing, receive everything.

Suffering makes valid the act of significance in the moment, in the moment we suffer, suffering has total significance. We feel in the act of suffering as if our suffering will never end, as if we had spent an entire life suffering, but all this gives way to a moment in which we do not suffer. Given enough time our suffering becomes insignificant. A person would do well to keep this in mind. They would do even better to take measures to reduce the factors that cause suffering in their lives.

Freundshaft, or Friendship has a valuable character only if one can be a friend oneself to others without seeking any friendship in return. On the other hand, one should be mindful, and not value and be distracted by those who suffer dishonorable habits and whose style of life we should not seek after.

We do not need to look beyond this life to judge the significance of most human relationships.

Hypocrisy is the rule in this world rather than the exception. If a person desires to be free of hypocrisy, they should imagine that everything they do is always being watched and judged by others or in more superb cases, by the person they would like to become.

Some of the greatest tastes in life are acquired (i.e., the taste for classical music, learning, exercise, solitude). A man should set himself out to acquire good taste. Above all, he should first set out to determine just what good taste is. What in the limited time of this limitation in its totality, that I call life, what will be most beneficent to me as Dasein?

Imagine: the mind exists isolated in a chaotic wasteland; four white walls, an even whiter ceiling and a floor that has no color surround it. It is this limitation that protects it from the harsh weather of insignificance that lies outside. Over time these walls slowly close in towards the center and when they meet they vanish along with everything else.
