　　(2018·湖南省十三校重点中学联考)When I was a small boy, I noticed that though many of the adults around me were wealthy and educated, they were not always happy and this sometimes led them to behave in ways, which I, as a child, thought strange. As a result of that, I decided to try to understand what happiness was and how best to achieve it. It was not surprising, then, that I decided to study psychology.

　　On arrival at the university, I was disappointed to find that academic psychologists were trying to understand human behaviour by studying rats in a lab. I felt that there must be other more useful ways of learning how we think and feel. I decided to build my career on trying to discover what made others happy. I started out by studying creative people such as musicians, artists and athletes because they were people who devoted their lives to doing what they wanted to do, rather than things that just brought them financial rewards.

Later, I expanded the study by inventing a system called "the experience sampling method". Ordinary people were asked to keep an electronic pager (传呼机) for a week which gave out a beeping sound eight times a day. Every time it did so, they wrote down where they were, what they were doing, how they felt and how much they were concentrating. This system has now been used on more than 10,000 people, and the answers are consistent: as with creative people, ordinary people are happiest when concentrating hard.
