meaning of life

- When man is happy, the meaning of life and other eternal themes rarely interest him. These questions should be asked at the end of one's life.

- But we don't know when life will end. That's why we're in such a hurry.
- Don't rush. The happiest people are those who are not interested in these cursed questions.
