Sell before build · pre-product validation
Design the sale before the product. An idea graduates only when it's sellable tomorrow with no code — a specific buyer, a real offer, and a test that pulls a dollar or a signature before a line is written.
Kill · pressure-tested
A falsified idea this week saved you months. And when an idea struggles, it's almost always the buyer that was wrong, not the concept. Re-cut who you're selling to before you touch anything else.
