Is failure a bad thing？ please help me recompose the speech,thank you very much! Good morning ladise and gentlmen: I'm very glad to stand here.Today my topic is"Is Failure A Bad Thing?" As many people think:there is no man in the world who succeeds in everyhhing.Even the greatest men sometimes make mistakes and failure. People's attitude toward it is quite different.some become entirely discouraged when they fail,others,on the other hand,take quite an indifferent attitude toward it. In my opinion,neither should we ignore it.If we don't pay attention to it,we may fail again and again.The right thing is to take lessons from failure and succeed the next time. So my dear friends.Don't be afraid to face failure.It is because that failure is the mother of success. Thank you for listening!
