Platão
He who is of calm and happy nature will hardly feel the pressure of age, but to him who is of an opposite disposition youth and age are equally a burden.
Eurípides
Youth is the best time to be rich, and the best time to be poor.
Aristóteles
Bashfulness is an ornament to youth, but a reproach to old age.
The young are permanently in a state resembling intoxication.
It is unbecoming for young men to utter maxims.
Youth is easily deceived because it is quick to hope.
Mark Twain
It is better to be a young June-bug than an old bird of paradise.
Too bad that youth is wasted on the young.
Leonardo da Vinci
In the days of thy youth seek to obtain that which shall compensate the losses of thy old age.
