I'm Sarah．I had little passion(激情)in my life before．But what happened the other day changed my mind．It was then that I learned how important it is to have a passion in life．
That day I went home in Mum's car．When Mum stopped at a red light，someone on the side of the road caught my eye．It was a man dressed in rags(衣衫褴褛)．He was homeless．That didn't interest me，because I had seen many people like him before．Those people usually looked unhappy and hopeless．
But this man was different in some way．He was not sitting alone with a sad look．Instead(相反)，he had a radio in his hand and was dancing happily to the music．The radio seemed to be the most precious (珍贵的)thing he had．
"Mum，why does that man have a radio although he's homeless?"I asked．
"Maybe he bought it，"she answered．
"But why didn't he use the money to buy food or clothes?He paid for something that he didn't need．
"Well,Sarah,sometimes food and clothes aren't the most important．"
That man must love music so much that he bought a radio instead of food or clothes．I soon knew that happiness is the key to life．
Since men I am always thinking of what is truly important in life．A home，a meal，clothes—these things are only part of the life．What we often forget is that we all need a light on a dark day．We all need a passion which gives a person the happiness they need to keep going．
