The first lines spoken by the old shepherd in William Shakespeare’s The Winter’s Tale are, “I would there were no age between ten and three-and-twenty, or that youth would sleep out the rest; for there is nothing in the between but getting wenches with child, wronging the ancientry, stealing, fighting.”

The critic Vladimir Stassov recalled that when the composers Nikolai Rimsky-Korsakov and Modest Mussorgsky “were still young men living together in one room…The piano could be heard, and the singing would start, and with great excitement and bustle they would show me what they had composed the previous day, or the day before or the day before that—how wonderful it was."

Joseph Conrad recalled, “It was in 1868, when nine years old or thereabouts, that while looking at a map of Africa of the time and putting my finger on the blank space then representing the unsolved mystery of that continent, I said to myself, with absolute assurance and an amazing audacity which are no longer in my character now, ‘When I grow up I shall go there.’”

Paul Cézanne’s father, a banker, was fond of telling his son, “Young man, young man, think of the future! With genius you die, with money you live.” At least this is according to Émile Zola, who recalled the words of admonishment in one of his letters to his friend Paul. The two had first met as teenagers at boarding school in the 1850s.

Gertrude Stein recalled that on the copy of her final exam for a class taught by William James she wrote, “Dear Professor James, I am so sorry but really I do not feel a bit like an examination paper in philosophy today.” She then left the room. The next day a note arrived from Professor James that said, “Dear Miss Stein, I understand perfectly how you feel. I often feel like that myself”—and then awarded her the highest mark in the course.
