How to get a good night's sleep

If you have little and work hard for what you have, you have more than those who have much and don't work for it.

"The sleep of a labouring man is sweet, whether he eat little or much: but the abundance of the rich will not suffer him to sleep." (Ecclesiastes 5:12)
