I agree strongly with the statement the author calls out. Stop believing in yourself and your amazing abilities, and embrace your incompetence. Stop talking about what a great marksman you are, look down at your bullet-ridden feet at long last, and embrace tools that make it harder to shoot yourself in the foot.

This weekend I found a collection of Javascript tests meant to evaluate one's abilities. I spent an hour trying to get the project to run, so I could take the tests, but it was all built on piles of Jello. A bunch of slightly-incompatible versions of libraries and frameworks and shit, so that 3 months after its release I couldn't use it. Stop the madness. Build shit to last and stop using things that make your next 5 seconds in emacs slightly easier at the expense of everyone else.
