This is one of the pieces of advice Donald Miller gave today. He gave a speech, followed with a question/answer time at the Abilene Christian University Summit. It was streamed live online and I watched most of it. During the Q&A time, one question was, "What advice do you have for new writers?"
"They sit down and they write every day."
Okay, let me dissect this advice for my own sake and anyone else that wants to be a published writer, but has a hard time making it happen.
Write. Every. Day.
