Something hit me on the head last week when I was walking along King's Road in Quarry Bay - and it was not a falling washing machine. Rather, it was a brilliant idea that could make me a very rich man. I am going to write a book. Those very same words knocked my mother off her feet 20 years ago - she was so proud. To her relief, I wanted to become a writer and not a triad gangster. Of course, my ambition was never realised because writing books needs ideas, and there were not many of those floating around in my creativity department - until last week, that is. And it's all thanks to my more 'conservative' colleagues. Over a dim sum lunch last week, I discovered some of my work-mates had little (if any) idea of, or confidence in, investing in the Hong Kong stock market. 'What if the stock market crashed tomorrow?' they said in chorus. This is like asking: what if Martians invade Earth tomorrow and kill us all? Talk about pessimism. So I explained to them that if they wanted to get rich they must have confidence in their judgments and, most of all, they must listen to my advice. Voila! The idea of writing a guidebook on how to invest your money wisely in Hong Kong. And why not? If you go into any attic bookshop in Wan Chai or Mongkok today, what are the first books you come across? Riveting works such as William Shakespeare's Romeo and Juliet? Jane Austen's Sense and Sensibility and Emma? Or Henry James's Portrait of a Lady? Correct. In both English and Chinese. But that is because these classics have been made into movies. If you were still awake after browsing through the above literary titles, you would come across the latest self-help books like How To Become Li Ka-shing In A Year, My Secrets of Success and Why Am I Rich And You Are Not? These authors, you see, are practically becoming rich and successful by writing about becoming rich and successful. We all know about Why Am I Rich And You Are Not? - you pay and the author gets rich. However, being a modest person, I will simply call my book An Amateur Guide to Making Money. And here are some useful tips that I may include therein. Tip number one: rob the banks before they rob you. Not recommended. However, if you are putting your entire savings in bank accounts, at least you are one step ahead of those who keep their money inside their mattress. My grandfather used to do that and guess what happened? My grandmother threw the mattress - and years of savings - away. Tip number two: shop at the stock exchange. Can be risky but in life what isn't? A popular form of investment in the territory. However, you will be surprised by common misconceptions among the public about stocks and shares. Some of these misconceptions are reflected in the questions: how can I make several million dollars in one day with $1,000? Is the Government floated on the stock exchange? Isn't the stock exchange down in Shamshuipo? Many people also have trouble grasping the logic of 'what goes up must come down'. The point here is to pull out of the market before it falls. People I know often do the reverse. Tip number three: foreign currencies. The exchange rate can be volatile. Judging from my own experience this can be the most risky form of investment. That is, whenever I buy a currency, its value drops immediately. Whenever I sell a currency, the next day its value climbs. So my advice is this: when I buy, you sell. And when I sell, you buy. Tip number four: racing and Mark Six. More a form of betting than investment. But punters will have you believe the more money you plough in, the bigger your financial returns. The golden rule is never go up to people the day after you have lost all your money and moan: 'Had I known blah, blah, blah, I would have won billions of dollars.' Well, you haven't, so shut up. After all, haven't you heard the Chinese saying: 'Had one known better, there would be no beggars.' Learn from your mistakes. Tip number five: marry someone who is both old - 90 or above - and super-rich. Short-term investment but almost a guaranteed return. As for me, I will stick to my book idea. You never know, one day you could be the one helping to make me a millionaire.
