If you write about a topic, situation or place you know well, care for, or are simply drawn to, your passion will come across to a reader and your story will ring true. You may have first-hand experience of growing up in a staunchly religious family or working in the crazy world of advertising, or overcoming handbag shopping addiction. Perhaps you've experienced a hijacking or a year-long trip through Africa. What do you know? What's meaningful to you? You come equipped with a huge bank of specialist knowledge on something. Use it.
