Rules for office politics

I came across this list and thought it's some adept advice:

• Keep it professional at all times.
• Play the game being played, not the one you want or think should be played.
• Don't make enemies.
• Don't burn bridges.
• Don't whine and complain.
• Don't intimidate superiors.
• Try to avoid going over your superior's head.
• Don't make others look bad.
• Don't criticize employees or bosses.
• Couch criticism in terms of employer's interests, not personal.
• Help others get what they want.
• Establish affiliations of mutual advantage with important people.
• Find common ground with others.
• Don't discuss personal problems.
• Selectively self-disclose.
• Don't assume anything will stay secret.
• Create win/win solutions.
• Keep employer's perspective in mind.
• Cultivate a positive, simple, accurate image.
• Force yourself to do difficult, uncomfortable or scary things.
• Be pleasant. Laugh and smile.
• Be assertive and tough when required, not aggressive.
• Don't oversell. Be natural. Develop your own style.
