The correction I would ask to apply is: If you're to practice
programming, you can't expect the necessary fuzziness of a layman's
understanding to be sufficient in specifying your program.

You need to know the specifics of what it is you're asking the computer
to do, and what it is you're *not* asking the computer to do, and the
difference between the two.
