Executive Council member Chow Chung- kong is busier these days than when he was chief executive of MTR Corp.
Since leaving the commercial sector, Chow has taken up an array of public service positions, the latest being chairman of the Independent Commission Against Corruption's advisory committee on graft, and convener of the Economic Development Commission's working group on transportation.
The 62-year-old Chow also chairs Hong Kong Exchanges and Clearing, and the Hong Kong General Chamber of Commerce, as well as being a Hong Kong Jockey Club steward, and a non-executive director of two listed companies.
A Hong Kong boy through and through, Chow was successful overseas, having worked in countries such as the United States, Britain and Australia.
He was knighted in Britain in 2000 for his contribution to industry, and his career continued to flourish after returning to the SAR.
Sharing his experiences, Chow often talks about having had to work summer jobs for living expenses when he was studying in America.
These included being a door-to-door encyclopedia salesman, which taught him that the winning qualities of a salesperson are not good looks or fancy talk, but determination and discipline.
To be successful, you must plough on despite the frustration of repeated rejections.
You must also have a plan and stick to it, or you will waste time and never achieve your aims.
During the three months on the job, he sold several hundred sets of the reference books, gaining valuable experience in overcoming career challenges.
He had to look for a job again a second summer in the United States. As he did not have any relatives there to help him, he just asked around.
Someone suggested he try Detroit where there was a booming car making industry. So he jumped on a Greyhound bus and went to the Motor City, where he became a faceless worker on a production line.
Those were trying days, but Chow is proud to have sweated through them.
No wonder there is a saying that to a young person, hardship is an experience more precious than gold. Siu Sai-wo is chief editor of Sing Tao Daily
