Your core - the answer to your why - will remain constant throughout your life

Your core - the answer to your why - will remain constant throughout your life. It is essential to your happiness, to finding the Oasis and to achieving any other goal you set for yourself. Your why will keep you headed toward the Oasis even when you are exhausted, distressed and anxious. Your why will keep your goal in focus and your vision clear, even when other ants tell you that the goal is no such a big deal. In fact, your why is almost as important as the Oasis itself - you can't get there without this vital step.
