Young people don't know what age is, and old people forget what youth was

If youth but had the knowledge and old age the strength.

He who wants to warm himself in old age must build a fireplace in his youth

It is often advantageous to forget. Forget your wincing humiliations, forget life's blows, and get on. For blocks in every direction, down every street in the city, people not yet old enough to have lines on their foreheads were laughing away memory, warmly ensconced in shrines of forgetfulness. Those who followed the word of God and those who preferred what the priests called "hoodoo" alike. People everywhere forgetting with drink or forgetting with religion or forgetting with the numbing quality of their many heaps of things. They looked forward and imagined rosy tomorrows, and gave up whatever horrors heckled their dreams, and listened to the pretty stories of whomever ruled their pulpit.

Young people tell what they are doing, old people what they have done and fools what they wish to do

Old age and treachery will overcome youth and skill
