“Some men and women, indeed, there are who can live on smiles and the word ‘yes’ forever. But for others (indeed for most) this is too tepid and relaxed a moral climate. Passive happiness is slack and insipid, and soon grows mawkish and intolerable. Some austerity and wintry negativity, some roughness, danger, stringency, and effort, some ‘no! no!’ must be mixed in, to produce the sense of an existence with character and texture and power.” – William James, Varieties of Religious Experience
