 All right, calling is important, but door knocking is also really important. It's a way to supplement your appointments. The days that you have no appointments or the days that you have a four hour gap between appointments, door knocking can bring activity that can help you reach your seeing 10 people because it's easy to get in front of people when you're door knocking. There are some agents that would prefer to just call, prefer to just door knock. I'm telling you the successful agents, we do both. We call, but we also door knock the leads that we can't get a hold of.
