Work and
thought are two
radically divergent approaches to
problem solving. If you just work at it, you are liable to find a
kludge, which will be
clumsy but
good enough for now. If you choose to think, you can find more
perfect and
elaborate potential
solutions, never tested because their hypotheses can always get
abstracted to one more level of perfection.
The more you think, the less you do, until eventually you can spend all your time thinking and getting nothing done.
