"He who feels that in his inmost being he cannot be compared with others, will be his own lawgiver. For one thing is needful: to give style to one’s character. This art is practised by him who, with an eye for the strong and weak sides of his nature, removes from it one quality and another, and then by daily practice and acquired habit replaces them by others which become second nature to him; in other words, he puts himself under restraint in order by degrees to bend his nature entirely to his own law."
