Self-confidence means the firm belief that you can do things well. If you want to succeed in doing anything, you must have confidence in your ability. Otherwise, you may hardly achieve anything. Some people always complain about how difficult their tasks would be and how incapable they are. They often refuse to have a try, and therefore have no opportunity to overcome difficulties in order to get themselves improved. Apparently, this shows their lack of self-confidence.

自信心就是坚定地认为你能够做好某事。如果你想成功，你就应当对于自己的能力十分自信。一些人常常抱怨说，他们的任务多么地艰巨，自己又是多么地无法胜任。他们经常拒绝尝试，因为根本就没有机会克服困难，提高自己。很明显，这说明他们缺乏自信。

There are several reasons why people feel frustrated or discouraged in face of difficulties. Firstly, they underestimate themselves. Second, they tend to overestimate the difficulties. Third, they are afraid of making mistakes or getting failures.

为什么人们在困难面前会感到沮丧和泄气呢？首先，他们低估了自己。其次，他们往往高估了困难。最后他们害怕犯错误，害怕失败。

It is important for young people to build up self-confidence. As a proverb goes,” confidence in yourself is the first step on the road to success.” we should make sufficient preparations and encourage ourselves before setting about doing anything in order to achieve success, which may help us gain self-confidence. We should have a right attitude toward our ability and should never look down upon ourselves. In addition, we don’t have to be afraid of mistakes or failures, for we can learn from mistakes and “failure is the mother of success”.

年轻人树立自信心是十分重要的，有则谚语讲到，“自信是通往成功的第一步。”为了取得成功，在着手做事的时候，我们应当做好充分的准备，不断鼓励自己，这样才能获得自信。对于自己的能力我们应当有一个正确的态度，永远不要小看自己。此外，我们还不要害怕失败和错误，因为失败是成功之母，我们可以从失败中学习。
