Do you know when your art gets boring? No, not when you have created enough of it. Art is infinite. It is when the artist has stopped making progress in her art that what comes on the canvas / presentation / blog / e-mail has lost its radiance.
So go slay the resistance that has been keeping you small. Just FYI, time will never be just right. So why not do it right now. Peter Diamandis has rightly quoted: “The best way to predict the future is to create it.” Now. For the world. Which will be superamazing because of you. Please. Pretty please.
