Don't think too much. There'll be time to think later. Analysis won't help. You're chiseling now. You're passing your hands over the wood. Now the page is no longer blank. There's something there. It isn't your business yet to know whether it's going to be prize-worthy someday, or whether it will gather dust in a drawer. Now you've carved the tree. You've chiseled the marbled. You've begun.
