Yeah, good or bad advice at just the right time can have quite an
impact.

In the under-celebrated "Minimal Perl"[0], Tim Maher notes in the
last paragraph of section 5.8:
<quote>
    In your own career, I'd advise you to develop an appreciation an
    appreciation and an aptitude for both the /quick-and-dirty/ and
    /elegant-and-formal/ styles of programming, and to cultivate the
    ability to produce either kind on demand, as circumstances
    warrant.
</quote>

Seems obvious, in retrospect -- but of course many things do with
the benefit of hindsight. For me, that articulated something that I
sensed was the right way to approach things, but was contrary to
much of the one-dimensional advice I had received up to that
point. It pairs well with one of the "lesser tenets" noted by
Gancarz: "Look for the 90 percent solution"[1].

In my own career, I've found I can often use the quick-and-dirty
approach to buy myself time to afford the "detour to build the
tools"[2] that could not be justified (to others) up-front. And
nothing gets it done faster than a shell script. Five or ten scrappy
N-line shell scripts that get the job done sub-optimally, and
lacking any real thought toward usability or generality buy time to
build better tools (usually more, better-written shell scripts). And
sometimes a scrappy script is "good enough" (for years, even).
