It was early morning. Peter Corbett helped Mark Wellman out of his wheelchair and onto the ground. They stood before El Captain, a huge rock almost 1.2 kilometers high. Mark had long dreamed to climb El Captain when he was a child. At the age of twentyone, he had fallen while climbing mountain, losing his legs. But he never lost his love for life.

Mark knew he couldn't finish the climb alone, but his friend Peter would be there to lend a helping hand. They thought it would take seven days to reach the top. Now Peter climbed about 30 meters up and hit a piton(岩钉) into the rock. Fastening(拴紧) one end of a 50meter rope(绳子) to the piton, he let the other end of the rope fall down. Mark caught the rope and fastened it to his belt. He next reached above his head and fastened a T-bar(丁字铁) to the rope. Mark took a deep breath, pushed the Tbar up almost as far as his arms could reach, and began the first pullup. High above, Peter let out a cheer, “You're on your way.”

For the first four days the two men progressed upward(向上) without accident. But on the fifth day, a very strong wind began to blow, making it hard for Mark to hold on to his rope. But Mark kept on pushing up the T-bar and pulling himself up.

It took them one day more than they had expected. But as the two heads appeared the group of people waiting on the top went wild with joy.

Mark Wellman showed that if you set your heart and mind on something, no wall is too high, no dream impossible.

案例：江崎公司日本泡泡糖市场年销售额约为740亿日元，其中大部分为"劳特"所垄断。但江崎公司对此并不畏惧，公司成立了泡泡糖市场开发项目组，通过专门调研发现霸主"劳特"有四点不足：第一，以成年人为对象的泡泡糖市场正在扩大，而劳特却依然把重点放在儿童泡泡糖市场上；第二，劳特的产品主要是果味型，而消费者的需求正在多元化；第三，劳特多年来一直生产单调的条板状泡泡糖，缺乏新型式样；第四，劳特产品价格是110日元，价格偏高，且需10日元硬币，消费者往往感到不便。通过调查分析，江崎公司决定以成人泡泡糖市场为目标市场，并制定了相应的市场营销策略。不久便推出了四大功能产品，司机用泡泡糖，加入了浓度薄荷和天然牛黄，具有提神醒脑、消除困倦功能；交际用泡泡糖，加入清凉薄荷，使你口气清新；运动用泡泡糖，内含多种维生素，有益于消除疲劳；轻松型泡泡糖，添加叶绿素等植物精华，可改善不良情绪。并精心设计了新颖包装和多种造型，价格定为50日元和100日元两种，避免了找零钱的麻烦。功能性泡泡糖问世后，象飓风一样席卷全日本，不仅挤进了劳特独霸的日本泡泡糖市场，而且占领了不菲的市场额，从0猛升至25%，当年销售额达175亿元。

江崎公司目标市场选择在哪里？
