Learning from many mistakes

Lately I have been taking a lot of photos compared to the usual rate. On Tuesday I snapped about 200 photos, and on Monday about the same. Within the month I have taken over 2000 photos. Of course, most of these (about 80%) went to the trash, but still there is a quite a collection. Have to see if I can sustain the rate. In any case, I have learned a lot from the mistakes. But the learning rate is slow in terms of getting really good photos. Often some technical glitch spoils an otherwise good shot. Such as focus a bit off, or the horizon not quite horizontal. Well, you learn from the mistakes.
