"You are too paranoid"

Something strange happened to me recently: a friend told me I was too paranoid when it comes to security. It was strange because he was the third person to tell me that in a couple weeks. Sure, I expect most people to call me paranoid, but these were all colleagues in the security industry. Is it time to worry when security professionals consider you too paranoid?

I use very long passwords for everything, even with the lamest accounts I have. I require my kids to use at least 14 character passwords on our home network and I'm considering issuing them smart cards. No one else, not even my wife, knows my network password.
