I think I found two great videos on youtube on the dos and don'ts of password creation.  A real must watch. I encourage everyone to watch these and then consider if your passwords are really safe.

  If you don't trust my link the video is called: "Password Cracking - Computerphile" also "Password Choice - Computerphile "

 If you know of a better video on password creation plz post it.

 Edit: would also like to recommend everyone watch "How NOT to Store Passwords! - Computerphile" and "Security of Data on Disk - Computerphile"
