I think my channel has a Disney-esque vibe. It's a friendly place.

My fan base is really, really young. They're the youngest demographic that you can track on YouTube: 13- to 17-year-old females. But the fan mail that I get in my P.O. box, they're all from moms and from kids who are two years old, three years old, four years old.

I've worked since it was basically legal to work. I was a waitress on and off for eight years. I worked at Sears; I worked at Abercrombie folding clothes. My dad really instilled good money management habits, and I've saved 10 percent of my paycheck, every paycheck, since I was 15.

My manager and fellow YouTuber, Mike Lamond, encouraged me to start a YouTube channel as a way to practice speaking, entertaining, and being more comfortable in front of a camera. In the beginning, I used an $80 dollar flip-camera and edited every episode myself.

Given that, and assuming that we begin to adjust to issues like climate change and the greenhouse effect, Denver's location in the center of the country becomes a tremendous advantage.

Climate change is obviously happening and there is obviously a man-made contribution.

Many business leaders are seeing the relationship between long term success and sustainability, and that's very heartening.

Like the other great revolutions, an environmental revolution will require sacrifices and lead to enormous gains. It, too, will change the face of the land and human institutions, hierarchies, self-definitions, cultures. It will take centuries. If it happens. There is no guarantee, of course.
