Here's a story：A man sees a butterfly.The butterfly tries to get out of its chrysalis（蛹）.Feeling sorry for it，the man decides to help it.He cuts the chrysalis and the butterfly comes out easily.Surprisingly enough，the butterfly is unable to fly.If the butterfly doesn't try hard to leave the chrysalis，it can't fly!The difficulties develop the power in the butterfly which makes it fly.Similarly，the challenges of life bring out the best in young people and make them fly.
When people are young，meeting and overcoming challenges will make them strong and ready to face life.When we look at successful people，we see that the most successful ones of them are those who have had to face the difficulties.One famous businessman who now owns many big supermarkets，used to carry clothes on his back and sell them from door to door when he was young.Another successful man is Dennis.His father died when he was only twenty.His father's death made him mature fast.He had to bring up a family of nine people.Ho took up the challenges and overcame them.Today his brothers and sisters are leading successful lives.
Sometimes challenges do not appear to us because we keep away from them.So some parents and teachers actively encourage young people to face challenges.They might organize some activities for young people which provide them with challenges，like rock climbing，camping，volunteer work and so on.However，just passing exams will not prepare a person for life.We must meet and overcome challenges.The young people of today will become the leaders of tomorrow.For countries to continue to be powerful，it is important that the young people learn to meet challenges and overcome them.
