Charlie Munger
Vice chairman of Berkshire Hathaway, 1978–2023
Life will have terrible blows, horrible blows, unfair blows. Doesn't matter. And some people recover and others don't. And there I think the attitude of Epictetus is the best. He thought that every mischance in life was an opportunity to behave well. Every mischance in life was an opportunity to learn something and your duty was not to be submerged in self-pity, but to utilize the terrible blow in a constructive fashion.
