I think it is quite common. Unfortunately, life doesn't wait for anyone to take a picture and we all have to learn to accept imperfections. If we don't, we're left with nothing and unable to move on and progress. I, for one, can't stand much clutter and love symmetry, geometric patterns, cleanliness in my images. Having said that, I have learned not to obsess over things I can't control or being bothered by the feel that an image could have been better, only if...

I know, it can be hard for some personalities, but the alternative is a total impairment of creative process.
