I'm reminded of Stephen Covey's Circle of Concern (everything you give you attention to) and the Circle of Influence (inside the CoC, everything you could have an effect on). He says effective people focus their energy on their Circle of Influence. Many people waste their time giving their attention to things they can't reasonably control, e.g. other people reactions, the news, national sports.
