ATH: Imam W. D. Mohammed(ra) The Need for Sustained Progress 1984

Understand this, that if you are going to make progress with other people, you are going to have to be of some value to them. And that goes for the business world. You come to me with some idea, you want to sell me something. It's got to be of value to me too. You want me to help you with something, want me to share the responsibility, want me to share the expenses or support you, it has to be valuable to me too. So learn that.
