What is your least favorite genre? What books do you sneer at in Barnes & Noble? What would you never write ever in a million years?
That’s what you’re going to write.
And you’re going to take it seriously. For at least ten minutes.
Now, you might think it impossible for someone who doesn’t like romance/YA/sci fi/horror/whatever to write romance/YA/sci fi/horror/whatever. With that kind of attitude, you’re bound to fail. (Ever watch The Great British Baking Show? Remember the guy who hated fruit pies? He kept saying it over and over… and his fruit pie was trash. And he got eliminated. Which is too bad because he was an excellent baker.) On the other hand, if you approach it as a challenge, if you decide to push yourself, you can rock it. (Ever watch Face Off? Remember when they made Monster High characters and the two humorous hipster guys could barely hold back their mockery of the challenge? Remember how they made an amazing fish monster glamour girl and won the whole thing?)
Okay, maybe you don’t share my taste in TV and it seems like I’m babbling. But I still think it’s a great challenge.
I’ll post mine in the comments, and I encourage you to post yours!
