Revision was always emphasized to me, but I never understood why. I always thought I was above it. After I became a programmer and had to look at old code I’d written, I finally understood why revision is so important.

Couldn’t my teachers have told me that revision is so important because we’re not qualified to evaluate our creations until they’re no longer fresh in our heads? It’s not an obvious concept, and I wish others didn’t have to learn it the hard way.
