"Object Writing" is a ten minute morning exercise that limits you to using sense-bound language rather than "internal" language (as coined by Andrea Stolpe in her class Destination Writing). This exercise gets you "tuned" to your surroundings and feeling your senses. Once you get the hang of it, you'll find yourself coming up with the sorts of details that really work in songs - especially in verses - to get listeners seeing their own lives in your lyrics. Many great song writers, like Gillian Welch, trace the roots of some of their most popular songs back to this exercise. Not to mention, it's just really fun and cathartic, too!
