Write a Book

So you want to write a book. Every book starts with the first sentence. If you cannot think of the first sentence then start with the second sentence. The point is to just get your ideas on paper. You can review it all later, but to starting can be a battle. 

In “Bird by Bird” author Anne Lamott advises just putting your words on paper.

“Perfectionism is the voice of the oppressor, the enemy of the people. It will keep you cramped and insane your whole life, and it is the main obstacle between you and a shitty first draft. I think perfectionism is based on the obsessive belief that if you run carefully enough, hitting each stepping-stone just right, you won't have to die. The truth is that you will die anyway and that a lot of people who aren't even looking at their feet are going to do a whole lot better than you, and have a lot more fun while they're doing it.” 
― Anne Lamott, Bird by Bird: Some Instructions on Writing and Life

Just start. Start writing. Start your journal. Start the blog. Write every day. Try to write at the same time each day. If you are a deadline person, give yourself one.  Write about anything. Write about a person you know well. Write about a childhood memory. Write.
