YouTube is a tremendous untapped resource...
Those who are tapping into YouTube are cashing in big time.
You don't have to make great videos or be a supermodel.
You need to create content that people find useful or entertaining.
You can also monetize your videos using Adsense and make money directly from YouTube itself.
If you go that specific route, then you don't have to sell anything to make money.
You'll only need to focus on creating videos that people will watch.
