If you are serious about photography with existing light, the act of using the camera and even merely carrying it forces you to, for the lack of better description, see things as they are. It opens your eyes, quiets your chattering brain, stops you from ruminating. It prevents you from being annoyed at the small things and keeps you in the flow.
Once you realize that a particular combination of countless factors—weather, air quality, time of day, time of year, place, angle of view, human or other subjects (or, as I often prefer it, lack thereof)—can create a vanishingly rare, one of a kind image, you just can’t help being in the moment and seeing those things; and once you have got it (captured light and developed it), it can be there with you as an additional memory trigger for years to come.
