Read poetry. Learn the beauty of your language through its masters. I would like to read a poem a day, but it often doesn’t work out that way.
I recently read Herman Wouk Is Still Alive, a short story by Stephen King that won the 2011 Best Short Fiction Bram Stoker Award, and was struck by how the author weaved poetry with the fiction to such stunning effect. (Spoilers not given intentionally, just read the story available in The Bazaar of Bad Dreams short story collection. Oh, and read some more poetry.)
