From opening the document, to when you write your first line can seem like an eternity. Sometimes words flow like a river and you wonder how you could ever not know what to write; to the time when you feel the river is dammed up somewhere far away up stream.
As a writer you have to know that when it comes it will come in a deluge but when it stops, it will always come back. Even the most inspired writers of words are sometimes completely dumb and absent of thought. So when you can’t write, give yourself a break.
There is always tomorrow!
