"We think our fathers fools, so wise we grow; Our wiser sons, no doubt, will think us so."
"Be it a weakness, it deserves some praise, We love the play-place of our early days; The scene is touching, and the heart is stone, That feels not at that sight, and feels at none."

Youth is the time of life when one is young. The word, youth, can also mean the time between childhood and adulthood (maturity), but it can also refer to one's peak, in terms of health or the period of life known as being a young adult. Youth is also defined as "the appearance, freshness, vigor, spirit, etc., characteristic of one, who is young". Its definitions of a specific age range varies, as
"We think our fathers fools, so wise we grow; Our wiser sons, no doubt, will think us so."
"Crabbed age and youth cannot live together; Youth is full of pleasance, age is full of care; Youth like summer morn, age like winter weather; Youth like summer brave, age like winter bare. Youth is full of sport, ages breath is short; Youth is nimble, age is lame; Youth is hot and bold, age is weak and cold; Youth is wild, and age is tame. Age, I do abhor thee; youth I do adore thee."
"Every stage of life has its own set of manners, that is suited to it, and best becomes it. Each is beautiful in its season; and you might as well quarrel with the childs rattle, and advance him directly to the boys top and span-farthing, as expect from diffident youth the manly confidence of riper age."
"Nature has done well and wisely, in not permitting a man to live forever and in bringing into the world ever new generations. An old person is a used-up machine [... He] has too many dogmas to [...] easily [...] believe in a new truth [...]; too many sympathies and antipathies [...] for him to come to love something unfamiliar; [...] too many habits to be able to settle on new ways. Let us add suspiciousness — the fruit of bitter experiences; a pessimism inseparable from all manner of disappointments; and finally, a general decline of powers from exhaustion [...]."
"Meek young men grow up in libraries, believing it their duty to accept the views, which Cicero, which Locke, which Bacon, have given, forgetful that Cicero, Locke, and Bacon were only young men in libraries, when they wrote these books."
"Young men are fitter to invent, than to judge; fitter for execution than for counsel; and fitter for new projects than for settled business;… Young men, in the conduct and manage of actions, embrace more than they can hold; stir more than they can quiet; fly to the end, without consideration of the means and degrees; pursue some few principles which they have chanced upon absurdly; care not to innovate, which draws unknown inconveniences; use extreme remedies at first; and that, which doubleth all errors, will not acknowledge or retract them, like an unruly horse, that will neither stop nor turn. Men of age object too much, consult too long, adventure too little, repent too soon, and seldom drive business home to the full period, but content themselves with a mediocrity of success."
