A、Living a life in the fast lane leads to success. B、We are always in a rush to do various things. C、The search for tranquility

How often do you say to people “I’m busy” or “I haven’t got time for that”? ［12］ It’s an inevitable truth that all of us live a life in the fast lane, even though we know that being busy is not always particularly healthy.
Growing up in New Zealand, everything was always calm and slow. People enjoyed the tranquility of a slower pace of life. ［13］ But after I moved to Tokyo and lived there for a number of years, I got used to having a pile of to-do lists, and my calendar always looked like a mess with loads of things to do written across it. I found myself filling my time up with endless work meetings and social events, rushing along as busy as a bee.
［14］ Then, one day I came across a book called In Praise of Slowness and realized that being busy is not only detrimental but also has the danger of turning life into an endless race. So, I started practicing the various practical steps mentioned by the author in the book, and began to revolt against the very idea of being too busy. ［15］ It doesn’t mean that my to-do lists no longer exist, but I’ve become more aware of the importance of slowing down, and making sure that I enjoy the daily activities as I carry them out. From now on, when someone asks you how your life is, try responding with words like “exciting” and “fun”, instead of the cultural norm that says “busy”. See if your experience of tranquility that follows.
