If your hunger for teaching, learning, researching, or communicating is high today, seek what lights your mental fire. In particular, pay attention to topics related to travel, spirituality, or philosophy that spark your interest. Signing up for a foreign language class or igniting a debate with a friend can open you up to new frontiers. But resist picking battles just for the heck of it. If you find yourself angling for intellectual victory, lay down your cerebral boxing gloves. Your instincts want to guide you toward illumination, not agitation.
