Be a joiner and watch your business grow. If not do it for your business. Your local church is a great place to meet potential customers. People like to buy from those who think like they do. If you're in the same group or club you are pre-approved by these folks.
Every business is people.
You need contacts and customers to be successful. If not, you are going to have to go out and find them. What that means is that once you have a customer in front of you they are looking for benefits or your product or service, not it's features. Customers who do not pay belong at your competitors. Customers who are loyal and do pay are the ones you want to retain.
