Someone once described collaborating to me like this: When you're writing by yourself, you're throwing a ball against a wall and catching it. When you collaborate, you throw the ball to another person – will they catch it? Fumble it? Throw it back to you in a totally new and unexpected way? Ultimately, it spices up the whole creative experience and makes you a better writer.
Unfortunately, not all co-writers are cut from the same cloth – some will be the best experience you've ever had, perhaps turning into lifelong friends. Some will make you pull out your hair, or feel you've wasted your time. So how to find collaborators that are a great fit? Here's just a few tips.
