“To allow oneself to be carried away by a multitude of conflicting concerns, to surrender to too many demands, to commit to too many projects, to want to help everyone in everything is itself to succumb to the violence of our times. Frenzy destroys our inner capacity for peace. It destroys the fruitfulness of our work, because it kills the root of inner wisdom which makes work fruitful.” — Thomas Merton (Via)
Good strategy is as much about choosing what not to do as it is about choosing what to do.
You have to know what matters to you.
