I wonder how one can slow down as a fast thinker. In school I used to be very fast with algebra and physics. But the hardest part was to get the numbers right. Just because my brain was too fast to think it through properly. Now when I'm writing code I still sometimes miss this "calculation parts" - some edge cases, maybe syntax, getting the general idea correctly. I did learn to deal with it somehow, but still I wonder how other people deal with it.
