General Colin Powell's Rules for Leadership

  1. It ain't as bad as you think. It will look better in the morning. 
  2. Get mad, then get over it. 
  3. Avoid having your ego so close to your position that when your
      position falls, your ego goes with it. 
  4. It can be done! 
  5. Be careful what you choose. You may get it. 
  6. Don't let adverse facts stand in the way of a good decision. 
  7. You can't make someone else's choices. You shouldn't let someone
      else make yours. 
  8. Check small things. 
  9. Share credit. 
10. Remain calm. Be kind. 
11. Have a vision. Be demanding. 
12. Don't take counsel of your fears or naysayers. 
13. Perpetual optimism is a force multiplier.
