Write Code for Your Worst Day, Not Your Best: A Case for Readable Code

A software developer argues that programmers routinely make a flawed assumption — that they will always be at their sharpest when maintaining their own code. Using the example of a colleague whose cryptic, uncommented codebase turned a five-minute fix into a six-hour ordeal, the author illustrates the real cost of prioritizing cleverness over clarity. The piece contends that code is most often read under pressure — at 3 AM, before a demo, or while sleep-deprived — making readable, well-documented code a practical necessity rather than a stylistic choice. Even developers who rely heavily on AI coding tools are urged to provide clear context and documentation, as it benefits both human collaborators and the AI itself. The author concludes that writing understandable code is ultimately a sign of professional self-respect, not a lack of technical skill.
