In fitness/health, relationships, and career there are people who take responsibility for their actions and emotions, and those who do not. “Responsibility” is “the ability to respond,” not guilt, blame, or shame.
I think the human race bifurcates at that point. The road splits. On one side are those who take responsibility, down the other are people who believe that they cannot change behaviors until the world changes, or there are “no good men/women” or that success is merely an accident.
