Do you really know the people in your network? Do they have special talents that you may need?
As the video says, we are not looking to just use these people for free help. No, they are people we can build a trust with and will not be scared to send them money to do a job, since we know them.
Sure you can ask them for help occasionally for the simple things, but you still have to respect that they have spent a good bit of time developing and building their knowledge.
