There is one type of illness in the world that has a severe effect on more people than anything else and is very deadly. If untreated, this illness could affect everything you do. What is this illness? Depression. Serious depression requires professional treatment. Self-induced depression is something each of us can change.

    Everyone's circumstances are different, but the causes of self-induced depression are common: low self-esteem, hurtful thinking and a bad attitude.

    So how can we change the way we think, feel, and have a cheerful attitude?

    First we must look at ourselves, truly and honestly examining our motives for what we wish to accomplish. If you are dissatisfied because you feel you haven't or can't do anything, then one step is needed—to set goals.

    Always start your goals relatively small and easy to attain. Think of them as sand; one grain may be insignificant(微不足道的) but as a group they form the beach. Once you have set and attained small goals for yourself, move on to slightly larger, more challenging goals.It takes not just setting goals but positive thinking. How can we obtain this?

    There are a number of factors that can make us think negatively and one of those is diet.In my opinion, a person who eats a lot of take-out and fast food is feeding their body junk. Start by eating better foods which give the body much NEEDED minerals. If your physical body is happy, it's much easier for your mental body or “thinking ability” to be happy.

    Next, exercise. Half an hour a day is recommended for positive well-being. Then think about good memories you had, or generally think of things that make you smile. Remember, everything you wear costs money but to wear a smile is free. A smile can be the difference between an average day and a great day.

    If you follow these steps, positive change is on the way.

    For an increasing number of students at American universities, Old is suddenly in. The reason is obvious: the graying of America means jobs, coupled with the aging of the baby-boom generation, a longer life span means that the nation's elderly population is bound to expand significantly over the next 50 years. By 2050, 25 percent of all Americans will be older than 65, up from 14 percent in 1995.The change poses profound questions for government and society, of course. But it also creates career opportunities in medicine and health professions and in law and business as well. “In addition to the doctors, we're going to need more sociologists, biologists, urban planners and specialized lawyers,” says Professor Edward Schneider of the University of Southern California's (USC) School of Gerontology（老年学）.

    Lawyers can specialize in “elder law”, which covers everything from trusts and estates to nursing-home abuse and age discrimination. Businessmen see huge opportunities in the elder market because the baby boomers, 74 million strong, are likely to be the wealthiest group of retirees in human history. “Any student who combines an expert knowledge in gerontology with, say, an MBA or law degree will have a license to print money,” one professor says.

    Margarite Santos is a 21-year-old senior at USC. She began college as a biology major but found she was “really bored with bacteria.” So she took a class in gerontology and discovered that she liked it. She says, “I did volunteer work in retirement homes and it was very satisfying.”

    What's the point of studying? It's something you might ask yourself if you're studying for a degree and you're struggling to complete homework or in an exam, especially if your friends seem to be out having a good time, or are working and earning lots of money.

    Many of us choose to go to university as a first step towards a good career but sometimes that career is to go to university as a first step towards a good career but sometimes that career is hard to achieve and graduates end up doing something they are overqualified for. With the increasing costs of university, students begin to ask themselves whether a degree path is the best route into a career. There is a need for much better career advice and guidance into employment in addition to university education.

    But other new research says that a degree will in the long run, earn you more. However there are differences in your earning potential. Dr Jack Britton says that "graduates of the 24 Russell Group universities earn an average of £33,500 after five years - about 40% more than those who studied at other universities."

    However, it has found it's not just the location but other factors that can play a part in what you can earn, such as the subject a student chooses to study. It discovered that five years after graduation, the income gap between students who studied the subjects that attract the highest and lowest salaries can be considerable. Graduates in subjects such as law, medicine, dentistry as well, tend to do well. And as they progress, the pay gap between these careers and others, such as the creative arts, widens. There are factors too that influence what you might earn: Five years after graduation, men earn on average 14% more than women. Also, a student's social background can have an effect, with those from better-off household much more likely to go to university and particularly a good one.

    But if you still feel university doesn't deliver the best opportunities then there are encouraging words from Alistair Jarvis, head of universities UK, who told BBC News that "Employs are demanding more graduates and graduates are half as likely to be unemployed as likely to be unemployed as non-graduates. There are many good graduate outcomes coming from universities" So may all that studying is worth it-after all 'no pain, no gain'!

    While most people have the idea that volcano eruptions are one of the most destructive disasters in nature, seeing a volcano erupt is a wonderful experience, and you can really feel the heat by climbing to the summit of Pacaya for a close-up view.

    There are guided tours every day up this highly active volcano from Antigua, giving travelers a chance to see Mother Nature at her most powerful. Pacaya is an easy drive from Antigua, a beautiful city with many colorful houses along its old streets that are turned into art-works during its Holy Week festival. No matter when you come to Antigua, you won't miss the Pacaya-tour companies.

    But climbing Pacaya is no easy job: it is 2,560 meters high, and reaching the summit takes two to three hours of seemingly one-step-forward and two-step-back movements. As you climb you hear the dull sounds of eruptions high above. Steaming, hot remains from recent eruptions begin to line the path as you near the active summit: the Mckenney Cone (火山锥). Just as though you were going to walk over to the edge of the cone, the road turns to the left and up to the relative safety of the old, inactive summit.

    Many tours are timed so that you arrive at the cone of the volcano in plenty of time for sunset and the full contrast between the erupting red lava(岩浆) and the darkening sky. On a good day the view from the summit is extremely exciting. The active mouth boils, sending red lava over its sides, and once in a while shoots hot steams up to 100 meters into the air. There is a strong bad smell in the air even if you take care to be upwind of the cone. As evening turns deeper into the night, the burning lava quietly falls down the side of the volcano. For you, too, it is time to get down.

    Two of the hardest things to accomplish in this world are to acquire wealth by honest effort and, having gained it, to learn how to use it properly. Recently I walked into the locker room of a rather well­known golf club after finishing a round. It was in the late afternoon and most of the members had left for their homes. But a half­dozen or so men past middle age were still seated at tables talking aimlessly and drinking more than was good for them. These same men can be found there day after day, and, strangely enough, each one of these men had been a man of affairs and wealth, successful in business and respected in the community. If material prosperity were the chief necessity for happiness, then each one should have been happy. Yet, it seemed to me, something very important was missing, else­there would not have been the constant effort to escape the realities of life through scotch and soda. They knew, each one of them, that their productivity had ceased (停止). When a fruit tree ceases to bear its fruit, it is dying. And it is even so with man.

    What is the answer to a long and happy existence in this world of ours? I think I found it long ago in a passage from the book of Genesis which caught my eye while I was looking through my Bible. The words were few, but they became memorably impressed on my mind. "In the sweat of the face shall you eat the bread."

    To me, that has been a challenge from my earliest recollections (memories). In fact, the battle of life, of existence, is a challenge to everyone. The immortal words of St. Paul, too, have been and always will be a great inspiration to me. At the end of the road I want to be able to feel that I have fought a good fight, I have finished the course, I have kept the faith.

    I recently came in contact with celebrity magazines. My family isn't one to give money for pictures of skinny, drunk celebrities with paragraphs about their relationships and shopping cart times. Thus, I was excited to finally get a chance to read about other people's attractive yet troubled lives.

    Right away I noticed how each magazine seemed to be a copy of the other. They had headlines and pictures that were almost the same. Still, the pictures of perfectly constructed faces with cute designers outfits going on with their daily lives made me read on.

Wait, celebrities taking their dogs for walk? Spending an afternoon at a park? All of these things seemed so ordinary—things my own family and I do together often. I suddenly realized how unextraordinary the people in these magazines were. They are simply normal people who happen to have a cool job and much money. For some reason, pictures of them doing things like buying milk at the store appeal to millions of readers. Then, when these regular people mess up, their mistakes is painted onto hundreds of newspapers and internet sites.

    What if every time we made a mistake, it was made public? Have you ever failed a test? Imagine seeing pictures of you on the front of a newspaper with headlines like, "Regular Schooling Isn't Enough". You'd be embarrassed. Now, I'm not necessarily taking the celebrity's side. I'm more realizing the fact that these people we were crazy about are just ordinary human beings with many photographs following them around. Role models? I'd think not. Personally, I'd rather look up to people in any community who have accomplished a lot instead of an ordinary person walking his dog in Berverly Hills.
