“They asked Wilson, once one of America's greatest speakers; You mentioned the importance of being prepared in a good speech. How far in advance do you start preparing for an eight-minute talk? The speaker said two months without thinking. What about for a ten-minute conversation? The answer is, it probably takes a month or so. Thus, as the speaking time increased, the preparation time decreased. The last question was: For a two-hour conversation? The speaker replied with a smile; I can start now!”
