Getting excited about something is not necessarily the same as being passionate about it. Someone can get excited about playing golf on a sunday afternoon, but Tiger Woods is truly passionate about it. Having passion about something means that your interest is more than casual. You give it your undivided attention!
What are you passionate about? What is it that excites your creativity and motivates you to take action? Ask God to help you find your calling in life, then do something each day to make it a reality.
