Barack Obama 2012: Espionage Golden Rules. Mikhail Kryzhanovsky, KGB

1. No mercy, no ideology, no emotions.
2. Intuition is nothing but the ability to watch and analyze.
3. No evidence is evidence in itself.
4. Distrust is a mother of security.
5. Never look as if you are sizing up the person — that’s a sign that gives away cops and spies.
6. Don’t start first if you don’t know the rules.
7. The way you act is the way you think — behavior is a system of codes (information) which could be calculated by the enemy. Watch your face — that’s a shop window.
8. Think fast, talk slow.
9. Avoid self-programming and never think bad about yourself.
10. Don’t smoke, drink or take drugs if it’s not necessary; spare your stomach from very hot or cold food or drinks; avoid too much noise and light.
11. Don’t be shy to lie — the more you lie the more people respect you.
12. Let people talk out and “empty their brains” — then load your information.
13. People never change — everybody wants to get pleasure and avoid pain.
14. “He knew too much” means “He talked too much.”
15. Never ask extra questions — wait. Wait and the object will get used to you and open himself — nobody can stay tense for long.
16. Lonely people live longer in espionage business.
17. “No exit” situation is the one you don’t like or don’t understand.
18. Avoid:
- personal enemies (they fix negative information on you)
- silent types (they notice and think too much)
- other professionals (they’ll blow your identity)
- extra stress (it damages your heart and blood vessels and that kills your brain and your ability to think )
- talking too  much
