When you start a business tell everyone what you do. It doesnt matter if you have never made a sale.
Whatever any business you do....just tell everyone you know ,why?
Because even you tell stranger what you sell ? why you don't tell you friends first?
And even the friend is just a normal friend, but if someday he meets someone who need to find the business you do. If your normal friend has no another better solutions..he will have chance to tell the guy what you do.
There is a friend of my father. He has a business in China .When he is a small fish. He works so hard but now...He just plays golf every day. Because he can get more business from golf.You don't need to sell something or push someone who to make business with you. You just play golf there and let someone who knows what kind of business you do. Then be a good guy. When someday who is new guy join the golf course . When he wants to find some business partner is what you do.The players inside will tell him about your business.
