Boredom is the root of all evil - the despairing refusal to be oneself.

Boredom rests upon the nothingness that winds its way through existence; its giddiness, like that which comes from gazing down into an infinite abyss, is infinite.

Only the noble of heart are called to difficulty.

So to be sick unto death is, not to be able to die-yet not as though there were hope of life; no, the hopelessness in this case is that even the last hope, death, is not available. When death is the greatest danger, one hopes for life; but when one becomes acquainted with an even more dreadful danger, one hopes for death. So when the danger is so great that death has become one's hope, despair is the disconsolateness of not being able to die.

The highest of all is not to understand the highest but to act upon it.

Men who not religious or artists are fools.

During the first period of our lives the greatest danger is not to take the risk. When once the risk has been taken, then the greatest danger is to risk too much. By not risking at first one turns aside and serves trivialities; in the second case, by risking too much, one turns aside to the fantastic and perhaps to presumption.
