Whenever someone says, "I always wanted to write a book. What should I do?"
I always answer with, "write the book."
The person usually looks at me like I'm holding back on a secret that will help transform the idea in his head into to a work of art. However, there's no chant or magical wand that gets the words on the paper.
A person can attend conferences, participate in workshops and study books all day long, but he will not produce anything until he sits his butt in a chair and puts his fingers on the keyboard.
Therefore, stop looking for the secret formula and get to work. It's the only way you'll get things done.
