Pareto-principle Memes

The classic 80/20 rule strikes again! You confidently estimate 4 weeks for a project, thinking you're being reasonable. Then someone asks for a breakdown and you casually split it: 2 weeks for 80% of the work, 2 weeks for the remaining 20%. Sounds balanced, right? Wrong. Your brain immediately realizes what every developer knows deep in their soul: that final 20% is where edge cases live, where bugs breed, where "just one more thing" turns into a three-day debugging marathon. That last 20% includes production deployment issues, cross-browser compatibility nightmares, that one API that doesn't behave like the docs say, and oh yeah—writing actual documentation. The Pareto Principle in software development is brutal: 80% of the features take 20% of the time, and the remaining 20% of features (polish, bug fixes, edge cases) consume 80% of your life force. Should've just said 6 weeks from the start.
