I spent two weeks building a data filtering system with custom views and display options.
Then I watched a user work.
She opened my carefully designed interface, used a browser extension to capture the table, dumped it into Excel, and started pulling in data from other sources.
She didn't need better filtering. She needed the data out so she could combine it with everything else she was working with.
An export function. That's what would have helped her. A few days of work, not two weeks of overengineering.
I'd built a solution to a problem I invented. The real problem was obvious the moment I sat next to her and asked "show me how you actually do this."
Now that question is where I start, not where I end up after the build is done.
User stories aren't requirements to satisfy. They're invitations to understand someone else's reality before you write a line of code.
