Stoics and Epicureans shared a great deal of their theory, too. They thought that the ability to enjoy life is thwarted by two big weaknesses: lack of control over emotions, and a tendency to pay too little attention to the present. If one could only get these two things right—controlling and paying attention—most other problems would take care of themselves. The catch is that both are almost impossible to do. So difficult are they that one cannot approach them head-on. It is necessary to sidle in from lateral angles, and trick oneself into achieving them.
