People buy you. They don’t buy your presentations, your service, or your product. Sure, there are exceptions, but people buy from you because they know you and trust that you are going to deliver. They aren’t necessarily buying your product or service, they buy you.
Now I don’t mean you are being sold into slavery. What I do mean is that as a salesperson, business professional, cat herder, or whatever you people are called these days, you are the person that is responsible for building your network. The larger your network, the more opportunities you will have to fill your funnel. Those opportunities will heat up once you begin to develop trust with people within your network.
