After all those months you put in, what was the hardest day like before you got that email? I bet there was a point where you questioned if any of it was worth it. That first sale is not just money, it's proof someone believes in what you built. Can you share what you did right before things clicked? The shift from working in the dark to having a real customer must have been huge. Tell me more about how you kept going when it felt like nothing was happening.
