A writer once said the way to write a book is to write one page a day. And at the end of 250 days you will have written a short novel. Isn't that the way life is: One day at a time. The trick is to write in the same way: One page at a time.
So Rule #3: Write a page every day whether you feel like it or not...And to hell with writer's block. And you will have that novel that you always said you would write at the end of it all.
And keep it a secret! Nobody will ever believe you did it one page at a time! After all, how long could that take?
