We all have that idea that we can't shake out of our head, the one that we think about in the shower or daydream about. Entrepreneur Job Gebbia, shares how his team grew their idea, Airbnb, into a national startup the hard way: by staying lean, "doing things that don't scale" like meeting users one at a time, and by taking one small step at a time.

Joe leads us in a storyboarding exercise that helped his team take ideas and push them into reality. If you'd like to follow along, download the Airbnb Storyboard Frame sheet and grab a pencil. When finished, tweet Joe at @jgebbia, and be sure to use the hashtag #nextstep.
