"Time stays long enough for anyone who will use it."

"Life well spent is long."

"Human subtlety will never devise an invention more beautiful, more simple or more direct than does nature, because in her inventions nothing is lacking, and nothing is superfluous."

"As a well-spent day brings happy sleep, so life well spent brings happy death."

"I have wasted my hours."

"A well-spent day is followed by a happy sleep; in the same way, a life well spent is followed by a happy death."

"I awoke only to find that the rest of the world is still asleep."
