What is it you wish YOU had thought of???
The Internet - Wish I'd thought of that. What's more fun than spending an entire day looking for naked pictures of Johnny Depp online (when you're supposed to be writing your book)? FINDING naked pictures of Johnny Depp online. BTW - if you find any, please let me know.
Threatening Your Customers - Wish I'd thought of that. Why, my troop's girl scout cookie sales would triple if I just showed up to sell them holding oily rags and accelerant and wiggling my eyebrows. Sopranos be damned. Nothing is creepier than dangerous little girls. Look at The Ring, the twins in The Shining, The Bad Seed...I'm right and you know it. Maybe I could get permission to print this on t-shirts...
Zombies - I wish I'd thought of that. They're enjoying a resurge lately, what with Jane Austen incorporating them into her books, YA zombie fic, and the new movie Zombieland. I wish I'd known the potential sexiness of decaying flesh with limbs falling off randomly. Leprosy is still out but zombie romance is here to stay.
