What should I test first, and how fast should I move?
You can already build the thing. That was never the hard part. The hard part is choosing which question deserves your time, and you keep avoiding that choice. This is not a skills gap. It is a fear dressed up as thoroughness. You test the easy things first because you're afraid of what the hard test might tell you. So you move slowly and call it being careful. Speed does not come from working faster. It comes from testing fewer things, chosen with more honesty, on a deadline that does not bend.
Find the one belief that kills your idea if it's false. Test that, not the parts you already feel sure about. Set a deadline before you start — days, not weeks. You are not testing your prototype. You are testing whether you understand your customer at all. Choose the hard question, not the safe one.
What changes unlock by starting
- You will have a ranked list of assumptions instead of a vague pile of doubts.
- You will set test deadlines in advance and hold to them.
- You will test what's dangerous first, not what's easy first.
- You will cut test time because you know what 'done' looks like before you begin.
