Everyone knows that failure always accompanies us in our life. No matter what we do, none of us can say we will surely succeed, because there is no such thing as plain sailing.
About failure, different people have different opinions. Generally speaking, on one hand, people think failure is the mother of success. They think we wont understand the profound meaning of success until we go through failure. On the other hand, for some people, failure is frustration. They think if a person goes through too much failure, he will collapse and lose confidence in his life.
In my opinion, failure is the footstone and catalyst of the edifice of success. You dont know what you have until its gone. If you have never lost it, and always get it easily, you will not cherish what you get and own.
