Are you writing a book? Angela Booth's written many books, both traditionally and self-published. Her tips will help you to become a confident author. Write every day: same time, same place. Separate writing your book from editing it. Before you know it, your book will be done.
Dorothea Brande's wonderful book, "Becoming a Writer", advises that you write in the morning, immediately after you get out of bed. Hilary Mantel and many other bestselling writers follow Brande's advice.
