It is in virtue of his own desires and curiosities that any man continues to exist with even patience, that he is charmed by the look of things and people, and that he wakens every morning with a renewed appetite for work and pleasure. Desire and curiosity are the two eyes through which he sees the world in the most enchanted colours...and the man may squander his estate and come to beggary, but if he keeps these two amulets he is still rich in the possibilities of pleasure.
Robert Louis StevensonThe very flexibility and ease which make men's friendships so agreeable while they endure, make them the easier to destroy and forget. And a man who has a few friends, or one who has a dozen (if there be any one so wealthy on this earth), cannot forget on how precarious a base his happiness reposes; and how by a stroke or two of fate --a death, a few light words, a piece of stamped paper, a woman's bright eyes --he may be left, in a month, destitute of all.
