Door Knocking For Leads?Scary@!

Does anyone agree with me that this is a much harder task than most make it seem like. Ive gone to many investing groups meetings, and read a lot of books and I have finally compiled a list of preforclosures. Ive even found some that are right in the town that I live in. Theres one problem. I am scared to death of knocking on somoneones door. Mainly because I dont know what all to say. I know that like after a while doing anything youll just learn your own technique and everything will just fall in place. Does anyone suggest any readings or have any suggestions to help me out a little,? **Please See My Profile**
