Youth is the season of credulity. Chatham.
Youth is too tumultuous for felicity; old age too insecure for happiness. The period most favourable to enjoyment, in a vigorous, fortunate, and generous life, is that between forty and sixty. Life culminates at sixty. Bovee.
Youth may make / Even with the year; but age, if it will hit, / Shoots a bow short, and lessens still his stake, / As the day lessens, and his life with it. George Herbert.
Youth never yet lost its modesty where age had not lost its honour; nor did childhood ever refuse its reverence, except where age had forgotten correction. Ruskin.
Youth no less becomes / The light and careless livery that it wears, / Than settled age his sables and his weeds, / Importing health and graveness. Ham., iv. 7.
Youth should be a savings-bank. Mme. Swetchine.
Youth to itself rebels, though none else near. 5 Ham., i. 3.
Youth would rather be stimulated than instructed. Goethe.
Youth, when thought is speech and speech is truth. Scott.
Youth will never live to age, without they keep themselves in breath with exercise, and in heart with joyfulness. Too much thinking doth consume the spirits; and oft it falls out, that while one thinks too much of doing, he leaves to do the effect of his thinking. Sir P. Sidney.
