Anyone for Tennis?

I'm still making steady progress with my book but, as ever, the real battle is the internal one.
My greatest enemy has always been self doubt, a common affliction especially for writers and would-be writers when it comes to believing in their work. For me it's a battle I think I'm winning. At the moment every negative voice is being slammed down by a positive one. But I think there are many fantastic writers out there who we've never heard of simply because they don't believe in themselves enough. And yet they are as good as and sometimes superior to many writers who are already published! I wish I could make them believe how good they are and convince them they can succeed. And if I ever do get published and get to teach creative writing I reckon it would be worth spending half the class working on people's confidence. It's a bit like the top tennis players - they all have the same skill set / level - in the end those that win are the ones with the psychological edge.
Regarding my work, I've promised myself that the book will get finished and resubmitted before the summer's out. Maybe it'll even be finished in time for Wimbledon?
