Light

Light is essential for a photographer and they go on at great length about having to have the "right" quality of light though I am training myself to follow one famous photographer who says  "light…any f*****ing light", or words to that effect :)  Cameras today are very sophisticated and can cope with a myriad of situations though, of course you do have to know just a bit about the settings to use.  I didn't have much light yesterday, it was changing very quickly so it was a bit of a waiting game.  Worth the wait though.
