Some people are committed to their dreams and work hard to achieve their goals． What is guiding them is a kind of illusion．Some people think that illusion is good for success while others argue that it is not so good because it may get people unrealistic． As far as I am concerned， illusion is necessary in our life only if it is encouraging and realistic．

There are several reasons．First of all， there is power in illusion． The illusion can lead people to the path they want to go on and it gives us passion． We need to live each moment wholeheartedly， with all our senses so that we can find pleasure in the fragrance¹ of backyard garden， the crayoned picture of a six－year－old， and the enchanting² beauty of a rainbow． The illusion can be enthusiastic³ love of life that puts sparkle in our eyes， a lilt in our steps and smoothes the wrinkles from our souls．

Secondly， we are born with wide－eyed， enthusiastic wonder as anyone knows who has ever seen an infant’s delight at the jingle⁴ of keys or the scurrying⁵ of a beetle⁶． It is this childlike wonder and illusion that gives enthusiastic people such a youthful air， no matter how old they are． For example， the famous cellist⁷ Pablo Casals would start his day by playing Bach. Music， for him， was an elixir⁸ that made life a never－ending adventure． As author and poet Samuel once wrote， “Years wrinkle the skin， but to give up enthusiasm wrinkles the soul.”

Lastly， people with illusions also love what they do， regardless of money or power or title． If we cannot do what we love as a full－time career， we can as do a part－time vocation⁹， like the head of state who paints， the nun¹⁰ who runs marathons and the executive who handcrafts furniture． We cannot afford to waste tears and energy and time on “might－have－beens”． We need to turn the tears into sweat as we go after “what－can－be”．

To sum up， God gives each bird its food， but he does not throw it into its nest． Wherever you want to go， just cherish your precious illusion and let your dream be realized．
