Article: When I was a child I never said, "When I grow up, I want to be a CEO," but here I am. When I look back on my career, I realize the road to becoming a CEO isn't a straight, clearly clarified path. In fact, no two paths are the same. But whether you want to be a boss one day or not, there's a lot to learn from how leaders rise to the top of successful companies. As this series of stories shows, the paths to becoming a CEO may vary, but the people in that position share the qualities of commitment , work ethic and a strong desire for building something new. And every CEO take risks along the way--putting your life savings on the line to start a software company or leaving a big business to be one of the first employees at a startup. I grew up in Minnesota, and learned how to be an entrepreneur from my father, who has run a small business for almost 30 years. I went to Georgetown University and tried a lot of business activities in college with varying degrees of success. And I always had a dream job pattern: to walk to work, work for myself and build something for consumers. I'm only 29, so it's been a quick ride to CEO. Out of college, I worked for AOL as a product manager, then moved to Revolution Health and ran the consumer product team. In mid-2007 I left Revolution Health and started LivingSocial with several other colleagues, where I became a CEO. Career advice: Don't figure out where you want to work, or even what industry you'd like to work at. Figure out what makes you do so. What gives you a really big rush? Answer why you like things, not what you like doing...and then apply it to your work life. Also, just because you're graduating , don't stop learning. Read more books than you did in college. If you do, and they're not, you're really well in a position to succeed in whatever you do.

Article: For new countries joining the European Union, and older ones getting used to their dark red passports, becoming "Europeans" is a bit like marrying into a large, eccentric family. Europeans have a lot in common but it is their differences, not their similarities, that attract the attention of sociologists and market researchers, and are more interesting. * 35% of Germans live alone, but only 9% of Spaniards. Perhaps this explains why Spaniards lead Europe in the habit of going out for a drink. * The British attend more adult evening classes than anyone else in Europe, and the Belgians least. So it can't just be the dark evenings. There are no figures on how many Britons go for a drink afterwards. If there were, they might be up at the top with Spain! * The British think black cats are lucky. Every other European country regards them unlucky. * The Dutch and Germans are the greatest caravaners , but the Germans like bigger beds in their caravans. * The French are the most athletic Europeans. Next come the Dutch. But the Belgians, just over the border, play fewest sports. * The Germans spend twice as much on heating as the Spaniards. Well, of course they do, it's colder. * Dutch husbands do the household shopping a lot more often than Italians or Spaniards. * The French are the champion public transport commuters of Europe. If you hate commuting, go and live in the Netherlands, where journeys to work are shorter than anywhere else. * The amount of direct eye-contact between strangers is three times greater among Spaniards than it is among the British or Swedes. Sharing a lift is torture for both the British and the Swedish. * No European countries really agree with any other about how to make good coffee. All of them are different. There are exceptions to all these rules. Deal with them in the spirit of my 8-year-old daughter. "If you don't understand each other's language, you just laugh a lot, and eat, and point at things."

Article: It's become part of the restaurant table setting: knife, fork, napkin and cell phone. Distracted dining is the new concern with customers constantly texting friends, uploading a Weibo photo of the meal they're about to chew down or emailing the boss. For many smart-phone users, it's hard just to focus on the meal and company at hand. Now, one restaurant in Los Angeles is giving diners a reason to turn off the digital world, by offering customers willing to check their phones at the door a 5-percent discount on their bill. Owner and chef Mark Gold of Eva Restaurant, located on Beverly Boulevard near N. Gardner Street, hopes this gives customers a way to truly sit back and relax, enjoy their meal and actually talk with friends and family in person. "For us, it's really not about people disturbing other guests. Eva is home, and we want to create that environment of home, and we want people to connect again," he explained. "It's about two people sitting together and just connecting, without the distraction of a phone, and we're trying to create an atmosphere where you come in and really enjoy the experience and the food and the company." Gold said applying the suggestion reminds him to avoid cell phone usage, too. "I'm guilty of it as well. When my wife and I go to dinner it seems like the cell phone is part of the table setting now. Every table you look at, it's a wine glass, the silverware and the cell phone," he joked. The husband and wife team runs Eva, a 40-person space with European flair. Gold said a little less than half take advantage of the deal, and no one has gotten upset about it. "I think once the server approaches the table and they're presented with the offer, they like the idea of actually talking to each other again," he said.
