This image and "The Gap" idea has been getting a lot of publicity lately - and rightfully so! It's an incredibly powerful and important message that is not spoken about often enough. It's also one of those things that can be "forgotten" once you get to a more comfortable stage in your development, which makes it even harder for people to understand it.
Here's a great, short video on The Gap by Ira Glass where I originally watched this idea.
