Closing is not a script, and Kelechi Ibe builds his best post around that. He argues the whole thing turns on finding what a particular person actually wants, since one wants time and another wants standing, and that hard selling fails because everybody has met it and learned to avoid the door.
He draws a distinction most people in the industry blur, between recruiting somebody and sponsoring them, and asks bluntly whether the people teaching sponsoring have ever sponsored anyone themselves.
