It has been suggested to me a time or two that I don't seem happy with, or enjoy, my photography because I'm always looking for ways to improve. Usually when the topic comes up, I'm totally blindsided by the idea because I love the beauty and challenge of capturing compelling images.
For me, improvement or personal growth is totally different from critique or criticism. And one of the things I love about photography is that the learning curve is steep and endless. I often refer to myself as a "student" of photography. Another belief which elicits responses that I'm too critical of myself and don't give myself enough credit. But the credit and praise comes from getting even a little bit close to capturing an image that does the beauty all around us justice.
So I can be aware that my talents will never truly capture the immense beauty of nature without feeling at all guilty of being inadequate to the task.
