I was so thrilled to unpack the advance copies of my new book, The Woman's Book of Joy, when the package arrived fom my publisher. I sat and stared at it, savouring the moment. Along with the feeling of elation and pride, however, I was surprised to experience a sense of trepidation. Knowing that it's part of my job as an author to reach out publicly to my potential readers - those who want inspiration in their lives - made me feel vulnerable. I suddenly felt overwhelmed at the thought of everything there was now to do. How was I to get to grips with social media?
