You need to network as part of the job. The people you will be meeting need to network just as much as you do - more if they work on commission. There are various tricks (note - do not try the "visualize them naked" trick if they are unattractive) to put yourself at ease, but they basically come down to lying to yourself.
You are talking to these people, not proposing to them. Remembering their names and a few odd facts about them that make them feel like they are important to you. That is the thing you must remember - networking only works if the people you deal with feel that they are important to you.
