Arthur Schopenhauer
Publisher: Dover Publications (2006)

If you accustom yourself to this view of life you will regulate your expectations accordingly, and cease to look upon all its disagreeable incidents, great and small, its sufferings, its worries, its misery, as anything unusual or irregular; nay, you will find that everything is as it should be, in a world where each of us pays the penalty of existence in his own peculiar way.  Amongst the evils of a penal colony is the society of those who form it; and if the reader is worthy of better company, he will need no words from me to remind him of what he has to put up with at present .  If he has a soul above the common, or if he is a man of genius, he will occasionally feel like some noble prisoner of state, condemned to work in the gallery with common criminals; and he will follow his example and try to isolate himself.'
