Read everything. Read fiction and non-fiction, read hot best sellers and the classics you never got around to in college. Read men, read women, read travel guides and Harlequins and epic poetry and cookbooks and cereal boxes, if you're desperate. Get the rhythm of good writing in your ears. Cram your head with characters and stories. Abuse your library privileges. Never stop looking at the world, and never stop reading to find out what sense other people have made of it. If people give you a hard time and tell you to get your nose out of a book, tell them you're working. Tell them it's research. Tell them to pipe down and leave you alone.
If everyone read just one more book, one more magazine, surfed three more news sites, added a few blogs, and added a newspaper to their monthly routine, I think we'd have a much more educated public in terms of current events and cultural awareness.
