It is currently said that hope goes with youth, and lends to youth its wings of a butterfly; but I fancy that hope is the last gift given to man, and the only gift not given to youth. Youth is pre-eminently the period in which a man can be lyric, fanatical, poetic; but youth is the period in which a man can be hopeless.
