VALERIE TRIPP says that she became a writer because of the kind of person she is. She says she’s curious, and writing requires you to be interested in everything. Talking is her favorite sport, and writing is a way of talking on paper. She’s a daydreamer, which helps her come up with her ideas. And she loves words. She even loves the struggle to come up with just the right words as she writes and rewrites. Ms. Tripp lives in Maryland with her husband.
