Chances are you've seen the work of our pal Gary Vaynerchuk, host of Wine Library TV. While you may know him as the guy who's tasted wines in a snowstorm or paired Chardonnay with Cap'N Crunch, deep down he's one seriously smart business guy.

His family wine shop in Springfield, New Jersey, went from sales of $4 million to $60 million in less than a decade for a simple reason: "Knowing thy audience," as Gary puts it. For example, he bet early and big that American wine drinkers would gravitate to high-quality, fair-price Australian and Spanish wines.

But Gary's success isn't rooted in single wine picks--it's all about innovation.

"I launched my family's liquor store business online in 1997," says Gary. "Wine Library TV wasn't the beginning or jumping-off point; it was the continuation of that trend of innovation."

And as Gary grew from offering straight-up wine advice to helping Fortune 500 companies develop social media strategies, he felt it time to come full-circle with his new book, The Thank You Economy--which is largely about the importance of making customers feel special.

"Crush It! positioned me too much as a motivational speaker," Gary says. "I'm a self-aware guy; I know that people view me as a very strong marketer, but perhaps one that is lacking substance. [But] I think when it's all said and done, people are going to say, 'Holy crap, Gary V. is a lot smarter than I thought he was.'" Read the online excerpt of the book, and you'll probably agree.
