A is a white-collar worker at a joint venture, feeling that his ambition has not been appreciated by his superiors. He often fantasizes about the day he could meet the CEO and have the chance to demonstrate his talents.
His colleague B had similar thoughts but took a further step. He investigated the CEO's commute schedule, calculated the likely time the CEO would enter the elevator, and deliberately took the elevator during that window, hoping to catch a glimpse of the CEO and say hello.
Colleague C went even further. He thoroughly researched the CEO's career journey, educational background, interpersonal style, and key concerns. He carefully crafted a few simple yet impactful opening lines. By taking the elevator at the calculated time, he greeted the CEO a few times. Eventually, one day led to a long conversation with the CEO. Shortly after, C secured a better position.
A是合资公司的一名白领，自感抱负未获上级赏识，常幻想若有一日能面见老总，展示才华该多好。
同事B也怀有类似想法，但他更进了一步：打听老总的上下班时间，推测其乘坐电梯的时段，并特意在此时搭乘电梯，期望能偶遇老总，借此打个招呼。
同事C则更为深思熟虑。他深入研究了老总的奋斗历程、毕业院校、人际风格及关注议题，精心设计了几句简洁而有力的开场白。他在预估的时间点乘电梯，在与老总数次简短问候后，终于有一天与之深入长谈。不久后，他便获得了更好的职位。
