Socrates is a great thinker and teacher.One day，he says to his students， "Today you are going to learn new exercise，swinging arms （擺臂） forward and then backward."
   He tells his students how to do the exercise.Then he asks his students to swing their arms 300 times every day. "Do you think you can do it"Socrates asks the students.They laugh and say，"Of course.It is not difficult."So all the students tell Socrates that they will do the exercise every day.
   A month later，Socrates asks his students，Which of you do the exercise every day？______ Socrates is happy that all the students do it.
   Another month goes by.He asks the class the same question，but only80% of the students put up their hands.A year goes by，and Socrates asks the class the question again.But this time，only one student puts up his hand.The student is Plato，He becomes a great thinker later.
   Well，doing one thing is easy but doing one thing every day is never.That's why some people can succeed（成功） but some can't.
