It encouraged us to visit Quora. com, the online question and answer community, to find out how users get the most out of every tank of gas.

    Light makes right

    Alex Elderfield noted that excess weight prevents an engine from burning fuel efficiently. "Only carry what is essential in your car, clean out any junk or necessary items otherwise you are paying for the fuel to cart these from place to place," he wrote.

    Driving smoothly — that is, not mashing the gas and then slamming the brakes later down the road — was a fixture of many responses. Quora user Clint Law agreed on that advice, who wrote, "Every little bit of kinetic energy that your brakes lose, your engine burned in fuel to build up." Overbraking should consequently be viewed as wasted acceleration. "That's really what kills your fuel economy," he argued.

    Keep the pressure up

    Keeping the recommended tire pressure for your car was another mantra among Quora users. Marlyn Rosent said she checked her tire pressure every time she filled up her SUV. Quora user Doug Dingus checks his tire pressure every weekend. “Less tire contact means reduced rubbing, requiring less fuel,” he said.

    Air conditioning or windows

    Though the summer heat get many drivers to roll up the windows and turn on the air conditioning, some people argued that running the A/C wastes too much gas. In between were many shades of grey.

    Achilleas Vortselas said it would depend largely on a car's speed. He wrote that as a general rule, people should drive with the windows down around the city and turn the air conditioning on when hitting the highway, where a car's aerodynamic(空气动力的) characteristics would be influenced by opened windows.

    More seriously minded people, however, said to travel as much as possible with windows up and the A/C off. Eddie Xue gets by with just a wisp of outside air. “Use the fan and open your windows every now and then at lower speeds," he wrote.

    An Exciting Dinner

    Looking for something adventurous? The Archipelago in London is just the thing for you. One of the most popular dishes in this restaurant is crocodile. Yes, you read it correctly, crocodile. If that is not daring enough for you, there are plenty of other dishes on the menu.

    A Restaurant with a View

    Want to enjoy the sights while you're eating? Try the Top of the World restaurant. At about 244 meters above Las Vegas, diners can enjoy a spectacular view of Las Vegas in this revolving restaurant. However, the real adventure starts at the end of the meal. That's when the customers are taken from their seats at ground level to the observation rooms in elevators that travel at a remarkable speed.

    Working or learning in a foreign country can be a difficult experience. The hardest part of working abroad isn't finding a place to stay or learning the language. It's learning to overcome the culture shock.

    These things are part of everyday life, and include many signs, gestures, facial expressions, and customs. When we enter a new culture, these cues (提示)are usually not present or so different that they're no longer understandable to us.

    "When a person enters a foreign culture," wrote Oberg, "all or most of these familiar cues are eliminated. He or she is like a fish out of water. No matter how broad-minded he or she may be, lots of props(支柱) have been knocked out from the environment."

    This is what happened to Lara, a young IT consultant (顾问) from America moved last year to their company in southern Europe. Three weeks after she arrived in Europe. Lara sent a desperate e-mail begging to return home. "The people are so unfriendly, "Lara wrote ,"They eat at strange hours and I'm starting to get allergic (过敏的)to the local food. I can't get anything done because their way of doing business is so disorganized and so inefficient and I have a terrible skin itch because of the water. I want to come home! "

    What Lara and other IT consultants meet on their first assignment abroad is a culture shock. While you can't prevent the culture shock from happening, you can take some measures to cut down its effects.

I often teach about happiness and what has become clear is this: There are some qualities unhappy people always have. Here are some of them.

 Happy people know life can be hard and tend to live through hard times. They take responsibility for how they got themselves into a mess, and focus on getting themselves out of it as soon as possible. Unhappy people see themselves as victims of life and stay stuck in the "look what happened to me" attitude instead of finding a way through and out to the other side.

    Most happy people believe in the good in people instead of thinking everyone is out to get them. Generally open and friendly towards people they meet, happy people foster(培养) a sense of community around themselves and meet new people with an open heart. Unhappy people are distrustful of most people they meet and don't think strangers can be trusted. Unfortunately, this behaviour slowly closes all chances of meeting new friends.

    Unhappy people believe someone else's good fortune is stolen from their own. They believe there's not enough goodness to go around and always compare others' against theirs. This leads to jealousy(嫉妒). Happy people know that others' good luck and superior circumstances are just signs of what they also can achieve if they try hard enough. They believe in unlimited possibilities and don't get stuck in thinking one person's good fortune limits their possible outcomes in life.

    There's only so much space between the two ears. Unhappy people fill that space with constant worry and fear. Happy people experience fear and worry too, but they make an important difference between feeling it and living with it. When fear or worry crosses happy people's minds, they'll ask themselves if there's an action they can take to prevent their fear or worry from happening and they take it. If not, they realise they're spinning in fear and they lay it down.
