It could be because I am normally looking at familiar subjects in familiar ways with an artistic spin. Because I am able to turn it around and blur unwanted sections, I can take a simple flower and showcase it's beauty. I really enjoy "discovering" a great composition on a very small scale.
Here's an example of a place I go often looking for subjects: It is a planter box where there is a repeating pattern through many boxes of the same flowers and foliage. I go from section to section looking for the best subjects with the best backgrounds. I can normally find something worthwhile and on this day I came home with this:

Not a bad day!
So next time you are out, be sure to look closely at what is around you!
