"Is your goal taking up so much of your attention that you reduce the present moment to a means to an end? Is it taking the joy out of your doing? Are you waiting to start living? If you develop such a mind pattern, no matter what you achieve or get, the present will never be good enough; the future will always seem better. A perfect recipe for permanent dissatisfaction and nonfulfillment."
