Willy Wonka Chocolate Bar

Here's a radical idea. 

When launching your next piece of long-form content, hide a candy bar in it. 

What I mean, hide something in the content to extrinsically motivate people to take the time to actually digest the content and experience the true value of what they're reading. 

Give them a Willy Wonka golden chocolate bar moment. 

What could you hide? Not sure. But make it meaningful and connect it to your brand and/or what your ideal customers care about.
