I think the clue is to be amazed. And when you are amazed by what are you seeing, you need only take camera and shoot. You need to be open and ready.
You can think about your work, you can return to some place again and again, in difrent time and difrent light. But more then about thinking this is about patience and humility.
You must learn, but not only about photography.You must to know and to understand. Without understanding you cann't be realy amazed... JK
