What do we talk about when we talk about money？ We often think about what we can buy with the money we have， what we can’t buy because we don’t have enough and what we’re planning to buy when we have more. We discuss the careers that bring us money and the expenses that take it away. We talk about our favourite shops and restaurants， the causes we support， the places we’ve been and seen. We share dreams that only money can make real. 
In short， we talk about everything but money itself. In daily life， money is still a major conversational taboo. This is a shame， because money is as interesting as the things it does and buys， and the more you know about it， the more interesting it is. 
（81） As a financial advisor， I’ve seen hundreds of people learn to control their money instead of letting it control them and watched as they increased as they increased their freedom， power and security by handling money consciously. Wouldn’t you like to know that you’ll always have enough money to live exactly as you want to？ 
You will never be powerful in life until you’re powerful over your own money. Talking openly about it is the first step.

What can we know from the second paragraph？（）
