For better effect also disconnect any phones from your work study where you have your computers. And when doing sensitive things also disconnect your speakers from your desktop (Power off button or remove the input cord to your soundcard and power cord from the wall). Don't use WIFI anywhere, unless you're in a bind. Keep all your tcp/ip connections wired and firewalled. Don't use wireless 2.4GHz phones either. Don't give the party van more remote info to collect or ways to penetrate your residence remotely.
Personal and sensitive communications should be made face to face, or signaled using gpg or through other encrypted communications methods. Make sure the person you're talking to isn't a retard carrying a cellphone in their jacket pocket, and make sure to ask them about this before you start your conversations, and if they have a cellphone tell them to turn it off and remove the battery before you start your conversation.
