Success is not easy to talk about because the word success itself has hundreds of definitions. For some it means power, for some it means wealth, for others it is fame or great achievements. But I have my own understanding of it.

Success means to try your best.
Many people believe that success means to win. In my opinion, it means to try your best when you do everything, no matter you will win or not. When you are taking part in a long-distance race, if you keep on running as fast as you can, you are successful, although you may be the last to pass the finishing-line. Because you have showed your best to others, and you have made I your greatest effort to be the winner.

Success means to work hard.
No one can succeed without any hard work. Karl Max was successful, because he spent more than 30 years writing the book "Communist Manifesto"; Tomas Edison succeeded, because he had experimented thousands of times to find the best material for lights. Every success calls for hard work. If you want to succeed, work hard first.

Success means not to lose heart.
No one can always be the winner. You will certainly lose or fail some day. It is important for you not to lose heart. A person who has lost heart is just like a tree without roots. It will be easily blown down by the wind. Nobel had failed many times when he was doing his experiments. Sometimes his lab was on fire and he was nearly killed. But he never lost heart and kept on trying. Finally he invented a new explosive. So when you fail or meet any difficulty, just believe in yourself, stand up and give the difficulty a heavy strike.
