“Innovators have to be open. They have to be able to imagine things that others cannot and be willing to challenge their own preconceptions. They also need to be conscientious. An innovator who has brilliant ideas but lacks the discipline and persistence to carry them out is merely a dreamer … But crucially, innovators need to be disagreeable … They are people willing to take social risks—to do things that others might disapprove of.” –Malcolm Gladwell
