You don’t have to explain your business to anyone, unless you plan on doing business with them. And all they need to understand is their part in your business. People don’t listen to understand, they listen to reply, to give you their opinion. The thing is, that people who don’t get it, will never get it and the people that do get it, will never ask. These are the ones that will help you grow. You can’t spend your life walking people by the hand and explaining your actions every step of the way.
