If there is one word I"m rapidly growing tired of, it"s passion. Not the sex and love type, but the workplace kind. Irately, it seems, I keep hearing career counselors advising the unemployed to identify and develop their passion. Then they need to turn that passion into paid work and presto! They"re now in a career they love.I know I"m being somewhat flippant, but I do wonder if passion is being oversold. Are we falling into a trap of believing that our work, and indeed, our lives, should always be fascinating and all-consuming Are we somehow lacking if we"re bored at times or buried under routine tasks or failing to challenge ourselves at every turnIn these economic times, fewer of us are worried about being fulfilled and more of us are concerned about simply being paid. But as switching jobs and careers becomes increasingly common, as whole professions are disappearing, we"re more frequently forced to ask ourselves what we want to do with the rest of our lives. That"s where passion comes in.Professor Wart, who co-wrote the book "The Joy of Work Jobs, Happiness and You", mentioned three factors for the workplace: supportive supervision, job security and the possibility of promotion, and fair treatment. He acknowledges that it is not easy to attain these goals, especially now. But it can still make a difference in your job satisfaction, he says, to examine what your strengths and needs are, and try, as much as possible, to match your work with those attributes. It doesn"t always mean getting a new job or career, but perhaps changing some things in your current employment. It would probably be better, Professor Warr suggested, to think less in terms of passion, and the inflated sense of drama that can go with that, and more in terms of job satisfaction or finding meaning in your work.The drive for passion or excitement, or whatever you call it, is deep in our genes. We feel good when the neurotransmitter dopamine is activated, and that"s what happens when we accomplish a given goal, said Gary Marcus, a professor of psychology at New York University. In fact, playing video games may not seem to be much of a passion, but if you"ve ever watched teenage boys going at it, their intensity and obliviousness to the outside world is the embodiment of flow. And that"s no accident.So maybe searching for a passion is not so bad. But it is also important to remember that there is no one way to find it, and someone else"s passion may be your idea of drudgery. And sometimes life—and work—is simply going to be putting one foot in front of the other. Or as Professor Warr said, "On the way to happiness, there must be unhappiness." It is implied in the second paragraph that ______
By now, the idea of airline baggage charges, extra legroom at a cost, paying for food and so on, has become for travellers a bit like the pre-flight safety explanation about how seat belts work. It may annoy. Or perhaps it has become so common that it no longer elicits much response. But these transactions are helping keep the planes flying, and they illustrate a market reality increasingly faced by a wide spectrum of consumers and businesses.Efforts by airlines around the world to increase revenue apart from ticket prices have grown almost tenfold since 2008 to $22.6 billion. And, even with that, the International Air Transport Association is projecting overall global airline profits will be down in 2012 for a second successive year to about $3 billion. That"s a profit margin of just 0.5 percent, so what some see as nickel-and-diming is viewed within the turbulent airline industry as pennies from heaven. "The whole economics of the business have been an absolute disaster since the fuel crisis of 2008," IdeaWorks President Jay Sorensen explained. "Airlines are just desperate for money."The economy has ensured that this desperation is not unique to airlines or even the travel business, where hotels may look to charge for a Wi-Fi connection that Starbucks will give you for free, or charge extra fee on top of the cost of whatever the resort"s room rate is and maybe tack on a housekeeping extra charge. You see this batteries-not-included mentality elsewhere. Cellphone companies that once advertised all-inclusive services look to sell data and voice separately. Banks try to assess new fees to cover costs they once absorbed."In an industry cycle, in the beginning, when you"re in a high-growth period, you tend to see a lot of bundling, giving a lot of things at one price," Jean-Manuel Izaret said by phone. "At the other extreme, when you are in the super-mature area, you"ll have low-cost providers entering certain markets with no-frills offers. So in a mature market, where low-cost challengers have come in and undercut the prices of established players, the only option for established players is to unbundle and price every little thing separately.""Airlines are going to have to be careful of nuisance fees, like checked bags and seating, and focus instead on inventing services that have not been offered before that people value," Sorensen said. That proposition is critical. But within a company the ability to generate revenue through a service often means more resources will be devoted to improving it. So the baggage service, for example, not only has benefited from fewer checked items in the system but greater investment in that system by airlines. Charging for specific services like baggage handling lets airlines invest to provide greater reliability for those who check a bag, without passing on the cost to customers who don"t. To supplement its revenues, airlines have ______
