You sure got us thinking.
If I look back to much of my 'early work', I see a lot of bad stuff. And shot way to much of totally uninteresting subjects.
But that is what I see now and I guess I needed to go through the stage of 'frame wasting'. When on a photographic trip I still shoot a lot of frames, but now I can see better than in the beginning (and in a few years I'll shake my head about my 2002 work).
The saddest truth is that most people shoot a lot without real critical editing and making new goals. One needs the drive to do better. Be it by shooting lots of frames or just one every day.
