I do not know how other photographers does it, but I like to walk around with my camera and when I have gotten a certain distance I close my eyes and play back the same steps I had taken, If I notice something doing so I go back and start taking pictures.
The same goes for places I have been before, I close my eyes and go through the same paths in my mind and think of locations to take pictures, often this technique leads to very interesting photos once I get out there and also I tend to notice things I did not when I was there first.
Weird or not, that is how I do it, if It works for others I do not know, but It might be fun to give it a try.
Often when you are out taking pictures it is just a natural place and angle to take pictures, but sometimes just turing around and tackling a unusual angle might yield much more interesting images.
An example is the image I took called "Arrival", the other way had a big calm lake with great reflections, a mountainrange in the back and really great looking shapes, but still turning around yielded the better image.
Not always the case, but trying those more "tricky" sceneries might just be what get you The shot.
Composition rules, Bleh!
Rules is really a wrong word to use, guidelines are much better, and if you think rules all the time before you know it that is all you do. I think it is important to shake it up, you do not need 1/3. land, 2/3. sky or opposite everytime, sometimes 1/7. land can be just what the doctor ordered.
Hope you might find anything useful in this.
Have a great day.
