Some words of wisdom on product design from Marimba cofounder Arthur van Hoff:
Over the years, I’ve learned that the first idea you have is irrelevant. It’s just a catalyst for you to get started. Then you figure out what’s wrong with it and you go through phases of denial, panic, regret. And then you finally have a better idea and the second idea is always the important one.
