Shoot with purpose

I got the opportunity to second shoot this beautiful wedding with Alicia Candelora, she taught me to shoot with purpose. Try shooting with purpose for a whole wedding and only getting the 100% most special moments, its much harder then you might think. Shooting with purpose made me think about my photography, and how I shoot. Do I over shoot? Is there such a thing as over shooting? What if you miss that special moment? When you shoot with purpose you retrain yourself to get the exact shots you want, to focus on only special moments, not just to get the so-so ones. Try shooting with purpose for a day.. let me knowhow it goes!! You may love it and it may help you develop your photography into what you want it to be, or you may hate it. Is there any perfect answer to shooting with purpose?
