The document provides guidance on drafting a Massive Transformative Purpose (MTP). It explains that an MTP should describe a better future for the world without specifying how to achieve it. Examples of well-structured MTPs from Tesla, Unilever, SpaceX, and Google are given. The document then outlines steps to test a draft MTP, including ensuring it has the right qualities and does not restrict the organization. A method called the "MTP Cocktail Party" is suggested to test if an MTP will attract the right people and communities.
