As a well-known proverb goes，self-confidence（自信）is the first step on the road to success．In my opinion，I really agree on it．Now in our daily life，the reason why so many people failed to cross the goals or realize the dreams is that they have no self-confidence in anything they do．As we know，nothing in our life can always run smoothly．As the hosts of the 21st century，we students should learn how to face the failure and challenge．So when we're in trouble，we should still keep having self-confidence in ourselves and never give up．
However，how does the self-confidence come？That depends on your psychological（心理的）factors．For example，you can try to find more about your advantages in order to believe your ability，because it can help to form the self-confidence little by little．On the other hand，there are many famous examples can strongly prove the importance of self-confidence．You can learn more about some of the famous people who have done great things with confidence．This will also reinforce（增强）your self-confidence．In a word，the key to success is that whatever you do，you should have self-confidence all the time．
Therefore，it can be said that self-confidence is the foundation of doing great things．If you always keep it in your mind，you will sure to forge ahead（高速前进）with great success．
