The most important reason is lack of success. Not being able to succeed affects one's self-confidence greatly. This is when one begins to doubt his own ability. In many cases one's self-confidence is low when he feels rejected by society. For example, a person who loses his job _ other people for fear of being questioned about his work. However, this isn't right at all. One needs to think along positive lines in spite of failures. After all it is your life and you have every right to live your life as you wish. The challenge lies in not allowing your self-confidence to decrease. _ When success doesn't come to you, you should not allow your self-belief to be affected. Always keep in mind that success is sure to come in time. So, there is nothing wrong with your ability. Whenever lack of success causes you to doubt your ability, don't forget to remind yourself that quick success does not last long. Also remember not to compare yourself to others. These tips will do a world of good to your confidence. In order to be self-confident, you need to have a lifestyle that is right for you. Create one and live a life as you want to. Leave others to themselves.

Example Input: Article: A Battery's Nightmare Portable electronics that can be carried about easily are only as good as their batteries and, let's face it, batteries aren't very good, especially when compared with, say, petrol, which packs 100 times a battery's energy into an equal space. That's why a large group of mechanical engineers (centered at the Massachusetts Institute of Technology, but with partners at other universities and companies) are hard at work in an effort to replace batteries with a tiny engine that runs on fuel. Imagine a battery-free life! When the fuel runs out in your mobile phone, you just fill up and go. The engine---about the size of a ten-cent coin---starts with a combustion chamber that burns hydrogen. Its tiny parts are etched onto silicon wafers in the same manner that computer parts are etched onto integrated circuits . The first engine is made up of five wafers. And since these wafers could be produced in much the same way as computer chips, they could probably be produced quite cheaply. But the _ in all this nice detail is efficiency. Tiny engine parts don't always behave like the bigger parts of the first engine. Something between the parts can slow down the works, according to Columbia University Professor LucFrechette, one of the engine's designers. Extreme heat from the combustion chamber is also a problem, often leaking to other parts of the engine. The scientists' goal is to create an engine that will operate 10 times better than batteries operate. Frechette says that a complete system, with all parts in place and working, will be set up in the next couple of years, but commercial models aren't likely until at least the end of the next ten years.

Example Input: Article: John Coltrane was born in North Carolina in 1926 and raised in the small farm town of High Point. As a young boy, he spent a great deal of time listening to the music of the black Southern church. Coltrane's father sewed clothes and could also play several musical instruments for his own enjoyment. The young Coltrane grew up in such a musical environment. And he discovered jazz by listening to the recordings of such jazz greats as Count Basie and Lester Young. When John was thirteen, he asked his mother to buy him a saxophone. People realized almost immediately that the young man could play the instrument very well. John learned by listening to the recordings of the great jazz saxophone players, Johnny Hodges and Charlie Parker. In 1943 John and his family moved to Philadelphia, Pennsylvania. He studied music for a short time at the Granoff Studios and at the Ornstein School of Music. He served for a year in a Navy band in Hawaii. When he returned, he began playing the saxophone in several small bands. In 1948, Coltrane joined trumpet player Dizzy Gillespie's band. Seven years later, Coltrane joined the jazz group of another trumpet player, Miles Davis.Then he began experimenting with new ways to write and perform jazz music, and explored many new ways of playing the saxophone.Some people did not like this new sound, while others said it was an expression of modern soul and represented an important change. By 1965, Coltrane became one of the most famous jazz musicians in the world. He was famous in Europe and Japan, as well as in the United States. He was always trying to produce a sound that no one had produced before. Some of the sounds he made were beautiful. Others were like loud screams. Miles Davis said Coltrane was the loudest, fastest saxophone player that ever rived. Many people could not understand his music. But they listened anyway. Coltrane never made his music simpler to become more popular. He continued to perform and record even as he suffered from liver cancer. He died in 1967 at the age of forty in Long Island, New York.
