I don't usually get star struck, but I met Sir Paul McCartney randomly on Sunset Boulevard a few years ago, and I lost it! I couldn't breathe, I couldn't think, and I didn't know how to speak. It was crazy. He was nice enough to talk to my family and me for 10 minutes, but I remember babbling away about nonsense.
The creative process is not like a situation where you get struck by a single lightning bolt. You have ongoing discoveries, and there's ongoing creative revelations. Yes, it's really helpful to be marching toward a specific destination, but, along the way, you must allow yourself room for your ideas to blossom, take root, and grow.
