Whether you're an aspiring songwriter trying to get in the game, or a seasoned pro trying to stay in the game, or for that matter, any hopeful fill-in-the-blank with an eye on a prize, it helps to have a passion on the side. Something to do while we're aspiring. Waiting for our big break. Or a little break. Something peripheral (or not so peripheral) that keeps us from being hyper-focused and obsessed. Something that makes us want to put eggs in other baskets. Perhaps that one basket could use some relief.
For creative types, giving it some space helps us gain perspective and return with fresh ideas and interesting words. It helps us avoid defaulting to our own redundant settings.
