What's the best life advice that someone gave you?

A wise man said to me:

1. Never date your friend's wife, for you expose yourself to death;

2. Before closing the door to sleep, check if you haven't forgotten something outside;

3. If your friend makes a living, be happy, and the doors will also open your turn;

4. Do not speak too much before your elders, but listen to much;

5. If you find a wise father or a wise mother, consider them as your true parents;

6. If your friend gets married, be happy because your turn will come;

7. If someone wants you to help them, don't hesitate if you have the opportunity to do so, because you never know about the future;

8. Do not criticize a poor, for he can become rich in the future;

9. Don't crave a rich man when riding a carriage, for you don't know the source of his income;

10. Respect your prayers there is a good sign that shows your gratitude to your creator the good God.
