Nature and architecture, 20 years amateur: 90+% are technically good; of those, probably 10% are aesthetically good; of those, 1% I really like. So 1/1000 overall that I really like.
I shoot found subjects, so I take some shots immediately so that I have a shot of the subject; these have a very high failure rate. Then I compose a few different ways, to get different framings, backgrounds and exposures. Some of these are deliberately not what I want, so I am always pushing the envelope and trying new things. Then occasionally there is a shot that I want (typically due to lighting, as I shoot only natural light), and it may take me a dozen frames to nail it.
I also do street and wildlife photography, but have much less practice at either of these. Street I can do technically, but like others have said, it's 1/1000 aesthetically (most shots are just boring). Wildlife I have not yet figured out technically, so I have yet to take a good photo.
