　　Problems are always encountered in one’s life to be faced and overcome. We cannot achieve anything with an easy life. One of the main decisive factors of success in life is our attitude. (22) While we cannot choose the adversity, we can choose our attitude towards it. Helen Keller was the first deaf and blind person to gain a university degree. Her activity and writing proved inspirational. She wrote, "Character cannot be developed in ease and quiet. (23) Only through experiences of trial and suffering can the soul be strengthened, vision cleared, ambition inspired and success achieved." Douglas Bader was 21 in 1931 when he had both legs cut off following a flying accident. He was determined to fly again and went on to become one of the leading flying heroes in the Battle of Britain with 22 aerial victories over the Germans. (24) He was an inspiration to others during the war. He said, "Don’t listen to anyone who tells you that you can’t do this or that. Make up your mind, you’ll never use a stick, and then have a go at everything. But never let them persuade you that things are too difficult or impossible." (25) The biographies of great people are littered with examples of how they took these kinds of steps to overcome the difficulties they faced. The common thread is that they did not become defeatist or depressed, but chose their attitude to be positive. 22. What can we do when we face difficulties in lives?
