I was not good in math in the first year of junior high schoo1.Having been failed so many times in math exams，I was anxious about the subject．Every time I tried hardly to work out a math problem，I was afraid of making mistakes，that really made me feel helpless．Luckily，I met a nice math teacher in second year. She told me that I didn’t need to worry about making mistakes because I could find out my shortcomings through my mistake．She always encouraged myself to try again whenever I make a mistake．Thanks to my teacher’s encouragement，I became interesting in math and made rapid progress．My experience proves that failure was the mother of success and that we can learn a lot from our mistakes．
When 24-year-old Hannah Brencher moved to New York after college，she was hit by loneliness. One day she felt so that she want to reach out to someone. And so she put pen to paper and started writing letters-letters to complete .
But these weren’t letters about how she was feeling. There were happy letters，all about the other person，not her. She would write messages for people to have a “ day " and tell strangers how brilliant they were， they thought no one else had noticed. Brencher began dropping the all over New York，in cafes，in library books，in parks and on the subway. It made her letter，knowing that she might be making somebody’s through just a few words. It gave her to focus on. And so，The Word Needs More Love Letters was born.
The movement is all about letters—not emails，but handwritten letters. Not love letters，written to a real beloved，but letters for strangers. They don’t necessarily say “I love you”，but they are . kindness—telling people they are remarkable and 15 and all-round amazing. It’s the sort of stuff that most people don’t really say out loud even to the people they ，let alone a total stranger.
Brencher’s initiative(初衷) has now .There are more than 10,000 people who join in all over the world. Last year，she gave a talk. In it，she talked about a university student who dropped letters around her campus，only to suddenly everyone was writing them and there were love letters hanging from the trees.
It’s a very cute idea. I know that if I was on the end of a letter like that，it almost certainly would put a on my face. So I decided to give it a try and see if I could do the same for someone else.

Stop wasting your time thinking of reasons for your failures and shortcomings. Instead，realize that the seeds of success were planted within you when you were born. Only you have the power to make those seeds grow.
The seeds，and the power to grow them，are contained in the most awesome machine ever created: the human mind. Success is a choice and not a chance. You were born a winner. You were born rich. You can be a success if only you make the right choice.
You cannot be successful without first developing your self-esteem (自信心). Your level of self-esteem is always based on the degree of control that you are able to exercise over yourself，and thus over your life. People with low self-esteem are people who do not believe that they have any power，or responsibility for their lives. They are always victims. They are leaves tossed (摇摆) by the winds of chance blown about with any sudden change in the weather.
You can exercise control over your life only to the degree that you believe you are responsible for everything that happens in your life. Failures think that everything happens by accident and chance. Successful people realize that they are responsible.
Everything happens as a result of something. If we can identify the cause，we can control the effect. We are responsible for what we choose to think and believe. One generally rises to the level that one expects. We are responsible for setting our expectations. Our success is dependent upon our level of confidence.
If you associate with positive-thinking people，you are definitely going to achieve success. On the contrary，the opposite happens. We are responsible for finding，planting，and nurturing (培育) the seeds that contain future victory，born from setbacks (挫折).
In short，in all areas of your life，whether they are financial，physical，emotional，or spiritual，you are responsible. Once you recognize this，accept it，and firmly believe it. You are on the road to success.

Alaska’s Arctic lakes now freeze later and melt earlier in the year than in 1950，leaving them easy to suffer water loss from evaporation(蒸发)and possibly adding to local warming，a new study finds．The winter ice season near Barrow，Alaska，is shorter than in 1950，researchers reported Jan.30 in the journal The Cryosphere.
Lake ice is also thinner each winter．The scientists surveyed 402 lakes on the North Slope，where permafrost (permanently frozen ground)and shallow lakes dominate the areA． In 2011，the lake ice was 38 percent thinner than in 1950，and 22 percent fewer lakes froze through to their bottoms．
“When we saw the actual numbers we were shocked at how dramatic the change has been，”lead study author Cristina Surdu，of the University of Waterloo in Canada，said in a statement．Surdu and her co-authors analyzed the changes in lake—ice thickness and ice cover with satellite images and climate model simulations(satellite images are only available from 1991)．
The climate models suggest the Arctic lakes froze almost six days later and broke up about 18 days earlier in the winter of 2011 compared with the winter of 1950．“The changes in ice and the shortened winter affect Northern communities that depend on ice roads to transport goods，”Surdu saiD． For example，every winter，oil companies build roads over frozen lakes to carry supplies to Prudhoe Bay．
“The dramatic changes in lake ice may also contribute to further warming of the entire region，because open water on lakes contributes to warmer air temperatures，”Surdu saiD． The Arctic is warming twice as fast as the rest of the planet，for reasons that may include its layered atmosphere，which traps heat，and the loss of sea ice and snow cover，which help reflect the sun’s energy when present．
