I have repeated this quote many times. Just three choices: do something constructive about the situation, leave it.or radically accept it. It's the latter option that, once we learn it, can transform our lives.
"You have to decide what your highest priorities are and have the courage - pleasantly, smilingly, nonapologetically - to say 'no' to other things. And the way to do that is by having a bigger 'yes' burning inside" - Stephen Covey
