Alfred, Lord Tennyson on youth

‘Tis better to have loved and lost / Than never to have loved at all.

Knowledge comes, but wisdom lingers.

Little flower — but if I could understand
What you are, root and all, and all in all,
I should know what God and man is.

But when I got to be 21, I was astonished at how much the old man had learned in seven years.

George Washington, as a boy, was ignorant of the commonest accomplishments of youth. He could not even lie.

When I was younger I could remember anything, whether it happened or not.
