Adopted from the following great insight shared by Daniel Pink from the book To Sell is Human

“Sales and theater have much in common. Both take guts. Salespeople pick up the phone and call strangers; actors walk onto the stage in front of them. Both invite rejection—for salespeople, slammed doors, ignored calls, and a pile of nos; for actors, a failed audition, an unresponsive audience, a scathing review. And both have evolved along comparable trajectories.”
