In the middle of the ocean is an island.
From above the island doesn't look like much. You probably wouldn't catch some celebrity sunning themselves while on a break from their box-office success. But, to me, the island is the best place in the world.
Why?
Did you see the monkey? No? Look closer. You just missed it jumping from that tree. What tree? The big jungle over there to the left. Darn. Now the elephant's blocking my view. Hang on, I'll move around it.
That's better.
If you squint (are you squinting?) you can see the golden temple in the distance. That's where the protagonist will have to go to find the treasure. But you know the villain will try to get there first.
Can you see the villain yet? I'm sure he's lurking around here somewhere. I can see his henchman behind that tent. What tent? The one on the beach. Did I mention the beach?
Why am I talking about imaginary islands? Because ideas are like an undiscovered island. There are hundreds of them, thousands, floating in the ocean of creativity. They might not look much from above, but your island can be whatever you want it to be.
You just have to look close enough.
