I agree that one should shoot the cliches, along with everything else. Living in Las Vegas, it's hard to see anything that hasn't been (isn't being) shot to death. For my shot of the Paris fountain, I waited until there were no people in the frame.
The subject has been well covered so far, and I agree with most of it, except for looking at a lot of other peoples' shots of the same thing. Maybe it's just me, but I tend to confuse the memory of someone else's' work with my own confirmation of a good shot, and end up shooting a copy. For me, spontaneity is important. A lot of potential shots present themselves, and I pass them over. Part of "vision" is to pause and look at the scene as a still, and shoot for yourself.
I also disagree with shooting things that abhor me. Driving a cab in 'Vegas, I see corpses, crashes, fights and fires and mayhem. What good is that? If a scene from life is not aesthetically pleasing, why would I wish to record it? My studies in light must remain free of those dark views, if I am to remain true to my own photographic aims. In presenting images for others to see, I should hope that it helps to turn their view away from the darkness in their own life view.
Shoot it all, and when you go back to edit later on, ask yourself what compelled you to pause, and notice that scene.
