Keith Ferrazzi. "Never eat alone" and other rules of networking (№ 382298)

It is the alpha and omega of leadership, sales, marketing, almost any activity aimed at encouraging others to do something. To be sincere means to speak the truth always, even when it is dangerous and can lead to far-reaching consequences.
