One can promise actions, but not feelings, for the latter are involuntary. He who promises to love forever or hate forever or be forever faithful to someone is promising something that is not in his power.
Friedrich NietzscheAnd if your friend does evil to you, say to him, ''I forgive you for what you did to me, but how can I forgive you for what you did to yourself?
Friedrich NietzscheLet us beware of saying there are laws in nature. There are only necessities: there is no one to command, no one to obey, no one to transgress. When you realize there are no goals or objectives, then you realize, too, that there is no chance: for only in a world of objectives does the word chance have any meaning.
Friedrich NietzscheEvery achievement, every step forward in knowledge, is the consequence of courage, of toughness towards oneself, of sincerity to oneself
