“Good friends, good books and a sleepy conscience: this is the ideal life.”

“We make war that we may live in peace”

“Make it a rule of life never to regret and never to look back. Regret is an appalling waste of energy; you can't build on it; it's only good for wallowing in”

“Don't take life too seriously; you'll never get out of it alive”

“The value of life ist not in the length of days, but in the use we make of them; a man may live long yet very little”

“There is no waste of time in life like that of making explanations”
