Building your network is the same as building a friendship group. You need to be friendly and helpful in any way you can. For example, if you were talking about a book you read on your recent holiday and someone sounded interested, send it to them. Or if you told someone you attended a sports club once a week which they had been looking into, invite them along as your guest. Small gestures will show your personality and build a sense of trust between your networks. However, do not do these things expecting a return; these things will come with time.
