Sooner or later, the ones who told you that this isn't the way it's done, the ones who found time to sneer, they will find someone else to hassle. Sooner or later, they stop pointing out how much hubris you've got, how you're not entitled to make a new thing, how you will certainly come to regret your choices. Sooner or later, your work speaks for itself. Outlasting the critics feels like it will take a very long time, but you're more patient than they are.
Seth GodinWhat makes someone an artist? I don't think is has anything to do with a paintbrush. There are painters who follow the numbers, or paint billboards, or work in a small village in China, painting reproductions. These folks, while swell people, aren't artists. On the other hand, Charlie Chaplin was an artist, beyond a doubt. So is Jonathan Ive, who designed the iPod. You can be an artist who works with oil paints or marble, sure. But there are artists who work with numbers, business models, and customer conversations. Art is about intent and communication, not substances.
