"It is not about solving puzzles and being the brightest kid in the class. It is about realizing that the complexity of software dwarfs even the most brilliant human; that cleverness cannot win. The only weapons we have are simplicity and convention. Tattoo that on your forehead in reverse so that you always see it reflected in the screen. What is truly decisive on the battlefield are attitudes: hard work, responsibility, and paying attention to reality instead of the voiceover in your head."
