The Ten of Diamonds suggests that you try, for at least a week, the practice of writing a new song every day. And don't spend all day on it! The Ten of Diamonds insists that you spend an hour at most, from start to finish.
To fit this writing chore into your daily routine, you might have to scale down your expectations. Your song might be very short, or very simple, or very repetitive. It might express a simple and mundane idea that you wouldn't ordinarily think of as song material. Whatever you come up with, it's okay, as long as it's a new creation.
The next day, write another song. It's okay if the second day's song is just a variation on the first day's song, as long as it contains some new element that you've never used before.
Even if none of the songs from your daily writing practice are good enough to use, this practice will strengthen your songwriting skills in a powerful way. You're learning how to write in an easy, comfortable, everyday way. The next time someone hits you with a real-world songwriting assignment, you'll be able say, "No sweat! I can handle this. I write songs every day!"
