The viewer holding a book now is the target. The title says read to speak better. The image says reading is not enough. That clash has to be settled. She holds the books the viewer owns, which makes the challenge feel personal.
How the packaging works
Title
The title promises three methods that turn reading into speaking gains.
Thumbnail
The image challenges the viewer's current habit, holding the books while denying they are enough.
Remix this

The transferable lesson
Let the image contradict the title and the click resolves it
