第4题

The Life I Desired That must be the story of innumerable couples, and the pattern of life it offers has a homely grace. It reminds you of a placid rivulet, meandering smoothly through green pastures and shaded by pleasant trees, till at last it falls into the vasty sea; but the sea is so calm, so silent, so indifferent, that you are troubled suddenly by a vague uneasiness. Perhaps it is only by a kink in my nature, strong in me even in those days, that I felt in such an existence, the share of the great majority, something amiss. I recognized its social value. I saw its ordered happiness, but a fever in my blood asked for a wilder course. There seemed to me something alarming in such easy delights. In my heart was desire to live more dangerously. I was not unprepared for jagged rocks and treacherous shoals if I could only have change — change and the excitement of the unforeseen.

第8题

企业家之所以成为企业家，靠的是开创事业的强烈欲望，这种欲望同画家和作家的创作欲望并无二致。企业家的欲望是让事情发生，让从前未曾有的事情发生。他所选择的途径是行动，或者说是经营．他的乐趣在于看到事情办得有成效，决定做得正确。使他的乐趣变得实实在在的是金钱。金钱是成功的标志，但未必是动力。检验这一点很简单：如果一个企业家突然得到他想要的那么多钱，他会停止营业呢，还是会用这笔钱去发展经营？历史表明，企业家多半会去开拓新的经营活动。
