The honest truth is that before you will ever be able to do business with anyone in your networking circle of friends they will have to like you and trust you. PERIOD!
If there is any hint of unproveable hype, you will blow your chances. Part of your job is to instill confidence in what you do and how you might be able to help others in your network. People have to be able to trust you. Trust is the foundation of a good relationship. Being honest is much easier than constructing fabrication.
