First, clarify your life—decipher your own personal riddle—by determining what it is you are destined to achieve, the direction in which your skills and talents seem to push you. Visualize yourself fulfilling this destiny in glorious detail. As Aristotle advised, work to master your emotions and train yourself to think ahead: “This action will advance me toward my goal, this one will lead me nowhere.” Guided by these standards, you will be able to stay on course.
