Sorrow is the child of too much joy

A day of sorrow is longer than a month of joy

You cannot prevent the birds of sorrow from flying over your head, but you can prevent them from building nests in your hair.

Don't hold to anger, hurt or pain. They steal your energy and keep you from love.

In the midst of great joy do not promise to give a man anything; in the midst of great anger do not answer a man's letter

You cannot prevent the birds of sadness from passing over your head, but you can prevent their making a nest in your hair
