Why Is It Like This Every Time

You're cruising through the project, knocking out features left and right, feeling like an absolute coding deity. Then BAM—you hit that final 20% and suddenly time warps into some kind of developer purgatory where every tiny bug takes three days to fix, edge cases multiply like rabbits, and that "simple" polish work somehow requires rewriting half your codebase. It's the universal law of software development: the Pareto Principle's evil twin where the last sliver of work devours your soul and 80% of your timeline. Why? Because the universe has a twisted sense of humor and deployment day is always tomorrow.
