Before you spend months building something nobody wants, run your idea through this validation framework based on Sahil Lavingia's The Minimalist Entrepreneur. It pushes you to test by selling a manual version first, not by writing code. You'll answer specific questions about who has the problem, whether they're already trying to solve it, and if they'll actually pay. The four weekend questions are solid: can you ship in a weekend, does it make life better, will someone pay, can you get fast feedback. It gives you a clear verdict with next steps. Honestly refreshing to see a framework that treats "my friends think it's cool" as the red flag it is.
