Building is the hardest and most rewarding process

Hey Hunters, This's Kais. First time building and launching a product. I wanted to say that it was an incredible experience that changed my perspective in so many ways, even through I've been a software engineer for over 7 years A few months ago, I started building VStamp out of frustration with Youtube. Today i'm launching it and I realized that - Theory disappears quickly when you start dealing with the real world. Important lessons can only be learned by doing - Managing yourself psychologically is more important than anything else - Marketing and UX are based on human psychology. What have you guys learned from your first launch? Curious to hear :D
