Beware beginnings.

慎始为上。

A journey of a thousand miles begins with a single step.—Lao Tzu

千里之行，始于足下。                          ——老子

An old carpenter was going to retire.The boss was reluctant to leave his good worker and asked if he could help build another house.The old carpenter said yes.But his heart was no longer in his work，and he used bad materials.When the house was finished，the boss handed him the key to the door.“This is your house，” he said，“my present for you.”He was shocked and ashamed.If he had known he was building a house for himself，how could he have done this？Think of you as the carpenter.Every day you knock in a nail，add a board，or a wall，and build it with your wisdom.Someday we'll find ourselves already trapped in the “house” we have built.Your life is the only creation in your life.It can't be rebuilt.Life is created by yourself!

During my first day at senior high school，I met my new teacher.She looked at me and said，“I am happy to have an international student in my class.” I was very excited.

One day，I came to the class about three minutes late，and she told me to write my name on a piece of paper and，beside it，the word “late”．In that way she could know I was late for the first time.At first，I was embarrassed and angry.Then I did not complain because she taught me an important lesson: time is very valuable.

I learned another important lesson during one of my classes—the day of the first exam.After I finished my exam，I did not review my answers because it was the end of the exam time.One week later，she returned my exam paper.I found that one of my answers was wrong.Even though the only choices were A，B and C，I chose D instead of C．I tried to explain my mistake to her，“I marked D though I knew C was the right answer.” However，she refused my request and told me，“I do believe you，but I am not going to forgive your mistake.This will encourage you to be more careful before you turn your papers in.” I was not expecting that from her，but she was completely right.
