This is a glass of water, tasteless, right? However if you add sugar, it will taste sweet, but if you add vinegar,（醋）it will become bitter. The same is true with our life. The taste of life is created by our choices.

If kindness is added to a stranger, you will have a friend; but if hostility（敌意） is added, you will have an enemy. If love is added to a pile(堆) of red bricks（砖） you will have a home, but if hate is add to those bricks , you will have an concentration camp（集中营）.So my dear friends，never complain that life is boring and the world is disappointing. If you don’t like the taste of your life, change it yourself.

Three years ago, I weighed more than 100 hundred kilograms which caused much difficulty in my life, like always failing my P.E examinations, always being laughed at by girls, and being terrified to speak in public. It was my grandmother’s encouragement that changed my life. She said “My dear, if you can’t change your appearance, why not treat it as your own style.” So I began to accept the new way of thinking and developed the confidence to make a difference and finally I found a totally new world.

So my dear friend, if faith, hope, love, endurance are added to your life, you will find the confidence to work out all your problems.
