Three milestones change everything, and none of them are named. The curve marks points one, two and three right where growth turns steep, so you can see the takeoff without knowing the numbers. The withheld figures are the whole click.
How the packaging works
Title
The title promises three unnamed milestones that change everything.
Thumbnail
The image marks points one, two and three on a curve that bends sharply upward.
Remix this
Use this when your list has a small number of unnamed levels. Mark them on a simple curve and keep the actual figures for the video. Naming even one on the image drains the pull.
The transferable lesson
Show the shape of the payoff, withhold the numbers.
