    I didn't think I had a passion(激情). I would sit in front of the TV all day, thinking about nothing but the next show. It was not long ago that I first learned how important having a passion is to life.

    That day I went with my mum to drive my sister to the gym. I was bored. Then, as my mum stopped at a red light, someone on the side of the road caught my eye（吸引我的世界）. It was a man dressed in rags (衣衫褴褛). He was homeless. That didn't interest me, for I had seen many like him before.

    But in some ways he was different. This man was not sitting down with a sad expression(表情). He had a radio in his hand and was dancing happily to the music. The radio seemed to be the most precious(珍贵) thing he had.

    "Mum, why does that man have a radio even thought（尽管） he's homeless?" I asked.

    "He bought it," she replied. I was still unable to understand.

    "But if he's homeless, why doesn't he use the money to buy food or clothes? He wasted it on something he doesn't need."

    "Well, Sarah, sometimes food and clothes aren't the most important things. We need happiness, too."

    The man must care too much about music to buy a radio instead of food clothes. I soon realized（意识到） that happiness is the key to life. Without it, there's nothing to look forward to.

    Since then I've never gone a day without thinking of what's truly important. A home, a meal, clothes—these things are only part of the picture. What's often forgotten is that we all need a pleasure, a light in a dark day. We all need a passion.

     Parents are creating an “I want it now” generation by indulging children’s every demand at Christmas，say experts.Youngsters are becoming increasingly selfish，claim the education analysts.

     Consumer­savvy children are forcing their families into racking up huge debts and risk becoming spoilt and dissatisfied in the future.

     Behavioural consultant Chris Calland said，“Parents are desperate to make Christmas into a magical fairy tale for their kids.There’s nothing wrong with that as such.The problem arises when it means always giving into all our children’s demands—even if they are beyond our price range or not age­appropriate.”

     Ms Calland，who runs “Santa Says No”  style sessions with  colleague Nicky Hutchinson，added，“Many of us go into so much debt providing the gifts our children want that we spend the rest of the year paying off the bills.Yet so often the parcels we’ve carefully wrapped，once opened，are just pushed away because the very thing our little boy or girl was once so desperate for，they have now lost interest in.”

     Ms Calland and Ms Hutchinson have drawn up a list of guidelines to help pare nts manage their offspring’s Christmas lists this year.They say that adults can actually improve their relationships with their children by resisting “pester (纠缠) power”．

     Ms Calland said，“All too often we say yes because we want an easier life when the fact is that we’re only building up problems for the future.We are helping create a generation of youngsters who are blind to the needs of others and the necessity of hard work.”               

   “Children learn fast—if we sometimes change our mind，they quickly realise it might be worth lying on the floor and screaming for it.Make sure you and your partner are working together on this.Be consistent.And try not to get caught up in competition with other families or friends.”
