One effective way of destroying happiness is to look at something and focus on even the smallest fault. It’s like looking at the tiled（铺瓦的）ceiling and concentrating on the space where one tile is_____ .

Once I heard a bald（秃头的）man said，“Whenever I enter a room，_____ I see is hair.”Once you’ve_____ what your missing tile is，explore whether getting it will_____ make you happy. Then do one of the three things：get it，replace it with a different_____ ，or forget about it and_____ the tiles in your life that are not missing.

We all know people who have had a relatively easy life，yet are essentially unhappy_____ people who have suffered a great deal_____  remain happy.

The first_____ is gratitude（感激）.All happy people are ______ .Ungrateful people cannot be happy. We tend to think that being unhappy leads people to______ ，but it’s truer to say that complaining leads to people becoming unhappy.

The second secret is______ that happiness is a by-product（副产品）of something else. The most obvious______ are the pursuit that gives our lives purpose-anything______ studying insects to playing baseball. The more passions we have，the more happiness we are likely to______ .

Finally，the belief that something lasting for a long time goes beyond us and that our______ has some larger meaning can help us to feel happier. We______ a spiritual faith， or a philosophy of life. Whatever your philosophy is， it should ______ this truth：If you choose to find the______ in every situation， you will be blessed；and if you choose to find the awful， you will be cursed. As with happiness itself， this is______ your decision to make.

   So let’s say that you’re sitting at a restaurant and when your food arrives, you take one bite and decide that something is preventing you from taking a second bite. No matter what the reason is, this dish is going back to the kitchen, and now it’s up to you to find a way to send it back politely.

First of all, the single most important thing to do when you’re sending something back is to do it immediately. If you eat half the dish before sending it back, the server and kitchen will believe that you really don’t need to send it back.

If a dish is too salty that it cannot be eaten, you should first let the server know what the situation is, and they’ll take it back to the kitchen and bring you a new one. Remember that it is not the server’s fault, so don’t take it out on them. Also, don’t be afraid that they’ll get angry at you, or someone will spit (吐) in your food. It’s their job to make sure that you’re satisfied, and if the kitchen clearly makes a mistake the server will be frustrated with the kitchen, not with the diner who has been served an inedible meal. A new dish will be cooked, and nobody’s going to spit in it.

There is, however, one example when you are sending back a dish which will really annoy both the server and the kitchen. If you order a pasta dish that contains pancetta but then send it back to the kitchen because you’re a vegetarian (素食者) and don’t know what pancetta is, and then congratulations because you’re one of the most unbearable types of customers a restaurant can have. A perfectly good plate of food is just thrown out because you don’t ask what pancetta is before ordering.

So the bottom line: Use common sense if you think that you need to send your dish back. If the kitchen do something wrong, then they’re on the hook for a new plate of food. If you do something wrong, then hopefully you’ve learned a lesson.

   With an improved economy，many travelers have been buying first or business class seats，leaving fewer for upgrades（升级）.Here are some strategies for getting a free upgrade.

1. Fly a lot.

This is the most common way to earn a free upgrade. Most airlines reserve some spaces for travelers who fly at least 5，000 miles per year. Five years ago，this meant half or more of domestic（国内的）first class travelers sat up front for free. But now，airlines are selling more high-price seats，so on popular routes it is not unusual for more than 20 travelers to compete for one or two upgrades. But on routes with fewer business class travelers，free upgrades remain more plentiful.

2. Use miles.

If you're not a frequent traveler but still have some miles to fly，you may be able to use them for an upgrade. Be careful，though，as many airlines now ask not just for miles but also a cash co-pay. One example: on flights to Europe，American Airlines charges 5，000 miles，plus $110，for a one-way upgrade from discounted economy class to business class. For most domestic upgrades，American Airlines wants 15，000 miles plus $ 75.

3. Get lucky.

Sometimes airlines overbook coach（经济舱），and a few travelers get no seats. Agents try to ensure the airline's most loyal travelers get the nod（被选中）. Agents usually have some flexibility to make sure the plane is full and takes off on time. So it's the easiest way for them to do it-they might upgrade someone else out of order.

4. Save a life.

Flight attendants don't usually upgrade passengers, even when empty seats remain. Doctors and nurses who answer an emergency call are sometimes an exception. If they comfort a passenger, flight attendants might allow them to sit in business or first class for the rest of the flight.
