One piece of the puzzle just isn't enough: either vision or preparation alone, without the other, won't get you anywhere. You might be fortunate to bumble along in chaos and frustration.
A few months ago, I made a side note about preparation. The story is about King Xerxes' search for a new queen, seeing as how Vashti had more than ticked him off. So now we have an episode of The Bachelor, except that the king isn't really a bachelor and none of this will be televised; although, you could likely guarantee that the gossip would have spread. The women gather at the palace and spend a whole year getting ready (beautifying) before they went to "see" Xerxes. Sure they had vision (let's get in with the King) but they also put some time into the preparation.
Greg's tagline reads: an up-and-coming, soon-to-be world famous photographer, world traveler and oddball. Today, I was reading his latest post on his journey to fulfill the "world famous photographer" bit. In the post, Greg refers to a few posts from David about the necessity of vision to balance nifty equipment.
I had to really look down deep inside and make sure it wasn’t just a desire for a newer, “better” lens. But, after some careful reflection, it was a decision based on the need to have equipment that would allow me to achieve my vision -- GregVision matters because it’s the destination that determines the choice of road map. -- Dave
