I spent 25 years in a scientific world, getting my degree and then as a computer programmer. The world I inhabited then was a very precise one. To get the computers to do exactly what you want and absolutely nothing else requires systematically thinking of all the possibilities and then catering for them. And then there is the users. The prompt says very clearly "Press Y to continue", so why have they typed in 37? A former boss of mine said he used to test the programs sometimes by sitting on the keyboard. I never saw him do it though.
And now I am a photographer it's all different. No more black and white right or wrong, it's all tones and shades of meaning, and "I wonder what happens if I do this". There are no lucky accidents in programming, but there are with photographs. And yet to get the very best results, one important thing is the same for both: you have to know what you want.
So, I am going to try and discipline myself to ask "What am I trying to do here?" before I release the shutter, every time.
Cheers, Tom.
