You need to be aware of your more tangible assets and don't leave your personal belongings unattended. Your purse, wallet, PDA, phone, laptop, etc., all contain personal information that can be exploited at your expense. Keep these items on your person at all times while you are in public. Shred documents that could be used to steal your identity, such as credit card offers. Don't leave mail in an unsecure mailbox - post bills and other financial or sensitive documents in a secure US Post Office box.
