I have a friend who lives by a three-word philosophy: Seize the moment. Just possibly, she may be the wisest woman on this planet. Too many people put off something that brings them joy just because they haven't thought about it, don't have it on their schedule, didn't know it was coming or are too strict to depart from their routine.

I can't count the times I called my sister and said,“How about going to lunch in half an hour?” She would gasp and stammer(结结巴巴地说), “I can't. I have clothes on the line. My hair is dirty. I wish I had known yesterday. I had a late breakfast. It looks like rain.”And my personal favorite response:“It's just Monday.”She died a few years ago. We never did have lunch together. From then on, I've tried to be a little more flexible.

Life has a way of going faster as we get older. The days get shorter, and the list of promises made to ourselves gets longer. One morning, we awaken, and all have to show for our lives is repetition of “I'm going to”,“I plan on” and “Someday, when things are settled down a bit.”

When anyone calls my“seize the moment” friend, she is open to adventure and available for trips. She keeps an open mind on new mind on new ideas. Her enthusiasm for life is contagious. You talk with her for five minutes, and you're ready to trade your bad feet for a pair of Rollerblades and skip an elevator for a bungee cord.

My lips have not touched ice cream in 10 years. I love ice cream. The other day, I stopped the car and bought a triple-decker. If my car had hit an iceberg on the way home, I would have died happy.

Now go on and have a nice day. Do something you WANT to, not something on your SHOULD DO list.

在某些系统中，存在非常复杂的对象，可以采用循序渐进的方式进行组合，将小对象组合成复杂的大对象。
以下实例展示了Builder(生成器)模式。该实例用来建立“文件”，文件内容包括：一个标题、一串字符以及一些有项目符号的项目。Builder类规定组成文件的方法，Director类利用这个方法产生一份具体的文件。图5-1显示了各个类间的关系。
