See in your mind’s eye where you really want to be in ten years’ time．Choose your own values, activities, and relationships rather than copying tubers．
While working with troubled teens, I used to haste them do a Ten Years game in the Future exercise．I asked them to write a letter to a friend as if it was ten years in the future．Most of these boys and girls didn’t think about the next week, much less ten years to come．This lack of “foresight”was a major reason why their lives were pretty messed up．But the real story is what happened to me．I did the exercise right along with them on many occasions, writing my dreams in detail．In my letter to a friend, I had moved to the country, built my own home, authored a book, and started my own business．
Over the next ten years, something magic happened．All my dreams became true, almost as if orchestrated （精心安排) by an unseen hand．I realized that something very powerful was happening, more powerful than expected．I did write books and start my business．We did move to the country and I did build my own home．
This letter to a friend will become a magnetic factor in your life．Your vision will guide you in your yearly goals, your monthly goals, and your daily activities．
You must write your letter as if it has already happened．For example:
“Leslie, I just wanted to make contact again and tell you about my life．I started my own gardening business in 2012 and it’s really taken off．”
“Dear Harold, I met the love of my life in 2016 and we moved to Hawaii where Frank works in a bookstore and I give surfing lessons everyday．We love it．”
Remember, describe all the details as if they have already happened．This will help you make it more real for you．

Life has changed in Mexico City．Streets normally filled with people are empty．One of the most popular professional soccer teams recently played a game in an empty stadium that can seat more than100,000 people．It's swine （猪）flu that has made life in Mexico City grind to a halt （慢慢停了下来）．
Seemingly out of nowhere, swine flu has caused confirmed deaths in 12 countries as of April 30．It has sent a wave of alarm around the world．Governments are trying to find ways to prevent further out-breaks．The World Health Organization has raised its swine flu global threat level to five out of six．
People may be familiar with bird flu, but they know little about swine flu．Swine flu is a contagious（传染性） respiratory（呼吸的）disease in pigs．It is caused by a type-A influenza virus．
Humans can also catch swine flu．The virus causes regular outbreaks in pigs, but people usually do not catch it．However, there have been cases of the virus spreading to people, and then from one person to another．
The symptoms of swine flu are similar to the common flu．They include fever, lethargy （无精打采）, lack of appetite, coughing, runny nose, sore throat, nausea（恶心）, and vomiting （呕吐）．The high proportion of young adults among the deaths is one of several mysteries about this virus．Most of the dead had lung damage．What caused it is not yet known．
The virus spreads the same way the common flu does．When an infected person coughs or sneezes around another person, the latter is put at risk．People can get the disease by touching something with the flu virus on it and then touching their mouth, nose or eyes．
There are medicines to treat swine flu．Doctors suggest using anti - viral drugs．They keep the virus from reproducing inside the body．
And there are vaccines for it now, several everyday steps can also help prevent the spread of the virus: washing hands frequently; avoiding close contact with people who are sick; and avoiding touching surfaces that might have the virus on it．
People may worry that they will get swine flu from eating or preparing pork．In fact, you cannot catch the virus from pork products if they have been properly prepared and cooked．Cooking food at temperatures of 71℃ kills the virus．
