We all have our own ways of sharing our life experiences with others.

Photographers use cameras, artists use brushes, musicians use songs and writers use stories.

Spencer Johnson’s story Who Moved My Cheese? shows changes exist in(存在于)our life. Life changes and so we do. We must change ourselves to face the changing environment, or we will fail.

Just look at the cycle(循环)of the seasons. Trees bud(发芽)in spring and in summer their leaves turn green. In autumn, their leaves start to fall onto the ground. When winter comes, there are no leaves on trees. Next spring the cycle begins again. Since we know there are cycles in nature, we can prepare for them. We know it is colder in winter and hotter in summer, so we can dress properly.

Since we accept the cycles of nature, we should also accept the changes in our life.

We can prepare ourselves for changes by becoming more flexible(灵活的). We can regard the changes in our life as chances. As we keep changing ourselves, we can keep up with the changes in our life.
