"When I hear people debate the ROI of social media? It makes me remember why so many business fail. Most businesses are not playing the marathon. They're playing the sprint. They're not worried about lifetime value and retention. They're worried about short-term goals."

"The reason I was able to grow my business was that every day, after producing 30 minutes of wine television, I spent 15 hours a day replying to every single person's e-mail and every single person's Twitter @ reply."
