Nothing beats the feeling of actually using the infrastructure you've poured four months into building. That's when it clicks—you realize what you're truly capable of. The real advantage? I can test any idea and know if it works within three minutes. Try it, see the results, iterate instantly. Most people don't have that luxury. They overthink, delay, hesitate. But when you're deep in the code, running your own infrastructure, every hypothesis becomes a quick experiment. No bottlenecks, no waiting for approvals. That rapid feedback loop isn't just efficient—it's a totally different way of working. You discover what works through direct action, not theory. That's the edge that most devs never experience.
