My kudos to Mr Wilson for a column which not only relates the fascinating and entertaining story of "getting into China" for the Wilsons' history-making tour, but also tips one of his biggest secrets. It may be the major factor of his success. And he gives it away in his first paragraph.
There are few people as successful as he in selling himself. As the article continues, he demonstrates the value of friendliness, courtesy, appearance, and attitude.
Entire success seminars don't have information quite as well delivered as this column does.
