Overcoming Difficulties ① Life is full of difficulties and obstacles, from birth to death. At times, Life seems like a hurdle race. We are sure of encountering hurdles, but almost always we are taken by surprise. It is necessary to accept that life in general is full of difficulties and adversities. This recognition is the first step. When faced with problems, we often feel, "I am the only one having such problems" Or, we tend to exaggerate our problems and regard them as most complex, most painful，and as an extreme case. But if we look around us, we find people in much worse conditions. As St. Augustine said, "I cried for boots, till I saw a man who had no legs." ② When faced with difficulties, we either complain or seek to dodge them. We behave like as ostrich in the desert. It is said that when there is a storm in the desert, the ostrich buries his head in the sand-hoping that the storm will go away if he ignores it-and finally gets buried under a heap of sand and dies. Some of us choose to pretend that the problems do not exist. We fail to realize that confronting and solving the problem-no painful the process-makes us grow. ③ Accept the woes of birth. It has many implied meanings. First, it means "accepting," i.e., being able to say that it is "my" problem and it is up to me to solve it. Many times we find ourselves putting the blame on others-parents, society or the circumstances of life. Nothing happens by chance, but all is the result of our past actions. There are times when what is needed is patience. We seek to come out of an unpleasant situation quickly. We must understand that if the cause had been operating for a long time, the effect also would last long-as even when the gas has been turned off, the burner remains hot for a long time. Similarly, we expect quick results; having put in the effort, we must be willing to wait. Patient acceptance of what is due to us makes us makes us take a step further in our development. ④ Once we have learnt to deal with a difficulty, the next time we encounter it, it ceases to be a difficulty. But, more often than not the cause of the problem is internal, i.e., within us, and often, it calls for a change. Often the difficulty is solved when we are willing to change—our way of thinking, our feelings, our likes and dislikes—and ready to adapt or adjust ourselves to a problematic situation or a person in life. We must realize that realize that change is inevitable, and always be mentally prepared for it. ⑤ Not all life's problems are such that they need to be dealt with all at once. Sometimes it is possible to take a step and wait for a long time. For instance, if the tap is leaking then we need to call a plumber as soon as we can. But having called him and having found that he can come only the following morning, we should wait patiently for the next 24 hours. In this period, people can get very anxious and go on talking about it to others. There are many such problems in life. It′s of great necessity to accept that life in general is full of（）
