Rich or poor，young or old，we all have problems．We can easily become unhappy（31）
we solve our problems．（32）
about our problems can affect how we do things at school or at home．So how do we deal with our problems？

．Think about Stephen Hawking，for example，a very clever scientist．He can't walk or even speak，but he regards his many physical problems as unimportant．Now he is known（40）
a great scientist in the world．We are probably quite healthy and smart．Let's not worry about our problems．Let's face the challenges instead．
