Youth is full of sport, age's 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.
William Shakespeare
All of us who are worth anything, spend our manhood in unlearning the follies, or expiating the mistakes of our youth
Percy Bysshe Shelley
There was no respect for youth when I was young, and now that I am old, there is no respect for age - I missed it coming and going.
John B. Priestly
Time, the subtle thief of youth
John Milton
Just at the age 'twixt boy and youth, When thought is speech, and speech is truth
Sir Walter Scott
Youth is a silly, vapid state, Old age with fears and ills is rife; This simple boon I beg of Fate - A thousand years of Middle Life
Carolyn Wells
The excess of our youth are checks written against our age and they are payable with interest thirty years later
Charles Caleb Colton
I would like to recapture that freshness of vision which is characteristic of extreme youth when all the world is new to it.
Henri Matisse
What Youth deemed crystal, Age finds out was dew
Robert Browning
Age is opportunity no less than youth itself.
Henry Wadsworth Longfellow
Memory in youth is active and easily impressible; in old age it is comparatively callous to new impressions, but still retains vividly those of earlier years
Charlotte Bronte
All natural goods perish. Riches take wings; fame is a breath; love is a cheat; youth and health and pleasure vanish.
William James
Youth is like spring, an overpraised season
Samuel Butler
Youth is too tumultuous for felicity; old age too insecure for happiness. The period most favorable to enjoyment, in a vigorous, fortunate, and generous life, is that between forty and sixty.
