"With two books a year, I don't have time for writer's block"

This quote by James Rollins speaks to the devotion and effort that is required to be a successful author. He is recommending that by writing 2 books a year, he does not have the high-end of experiencing author's block. This implies that he is continuously composing and producing material, and that he is disciplined in his technique to writing. He is recommending that author's block is a high-end that he can not pay for, and that he needs to remain concentrated and efficient in order to meet his objectives. This quote is a suggestion that writing is a craft that requires dedication and effort, and that author's block is something that can be prevented with the ideal approach.
