Life is full of difficulties, from birth to death. When we face with problems, we often feel, “I am the only one having such problems.” Or, we exaggerate (放大) our problems and regard them as most painful. But if we look around us, we find other people may be in much worse conditions.
Life is not always full of smiles and flowers. Every person has his own difficulties no matter who and where he is. So it's very important to have a correct attitude in your life. Only with the correct attitude can you face up all of your difficulties and finally overcome (战胜) them. First, you have to believe in yourself. That's the secret of success. Second, don't blame others when you have difficulties, because it can neither help you avoid difficulties nor help you solve them. And the most important thing is that don't run away or give up. Use your ability to clear the difficulties that appear in your life. Third, remember how you overcome the difficulty because it may help you avoid similar trouble next time. Just take it easy, enjoy the life even it's full of difficulties.
