Every time you jiggle a door handle to make sure it's actually locked, you're doing QA. Every time you send a test text to yourself before a big group message, you're doing QA. Quality assurance isn't a tech thing — it's a human instinct. We poke, prod, and double-check the things that matter to us because failure has a cost. The people who do this professionally just apply that same instinct to software before it reaches you

Think about the last time you refreshed a form submission email just to confirm it went through. Or read a text back to yourself before hitting send. That pause — that small moment of "wait, let me just check" — is the entire spirit of manual QA. The difference is that a professional tester builds that pause into a system, runs it on purpose, and documents what they find. You're already halfway there.
