There are 4 types within the Human Design System. Each type plays a critical role in the interaction of the human species. Generators and Manifesting Generators have powerful internal motors to churn out work, Projectors have vision and projective energy to guide, lead and manage, Manifestors are stirring the pot, creating and initiating action to create and manifest new things. Reflectors act as a mirror to society to show us how and what we are doing. If everyone on this planet lived their type and strategy of the design they were given, there would be a lot less struggle and discontentment in the world.
