Consider change at every level—individual, organizational, and societal. Maybe you want to help your brother beat his email addiction. Maybe you need your team at work to act more frugally because of the times. Maybe you wish more of your neighbors would bike to work. Usually these topics are treated separately—there is “change management” advice for executives and “self-help advice” for individuals and “change the world” advice for activists. That’s a shame, because all change efforts have something in common.
