Never underestimate the power of intention. The Artist's Way advocates writing them out every morning. There was some study about molecular changes in bottles of water affected by different words printed on the outside. "Love" or "Hate" would cause measurable changes in the structure of the water by those who read those words. I don't know about that, but I do know that intention influences outcome.
It is always my intention, camera in hand, to be "professional" (serious, focused, open), to use my senses other than vision-- because for example, listening can lead to some of the best photographs, and to check my ego at the door (every time I get cocky I miss something). The message here is about attitude. No matter what form of discovery one embarks upon, if there's a defined intent, there'll be a more tangible result.
