“You must build up your life action by action, and be content if each one achieves its goal as far as possible—and no one can keep you from this. But there will be some external obstacle! Perhaps, but no obstacle to acting with justice, self-control, and wisdom. But what if some other area of my action is thwarted? Well, gladly accept the obstacle for what it is and shift your attention to what is given, and another action will immediately take its place, one that better fits the life you are building.” —MARCUS AURELIUS, MEDITATIONS, 8.32
