Indeed, I have observed one ingredient, somewhat necessary in a man’s composition towards happiness, which people of feeling would do well to acquire; a certain respect for the follies of mankind: for there are so many fools whom the opinion of the world entitles to regard, whom accident has placed in heights of which they are unworthy, that he who cannot restrain his contempt or indignation at the sight will be too often quarrelling with the disposal of things to relish that share which is allotted to himself. 
Henry MacKenzie, The Man of Feeling
contentment, happiness
