They were both busy with their respective work and sometimes they had to make business trips at weekend. The only time for their so-called home life was restricted to the few hours after work. Indeed, they had made a lotof money, but they got fed up with such a fast-paced lifestyle. So soon after their daughter was born, they decided to change their lifestyles.They traded their two full-time careers for two part-time jobs, and tried hard to curtail their consumption. They sold their splendid house and moved into a smaller but pretty and energy-efficient home designed by themselves. They downsized their possessions and discarded all the expensive clutter. They also sold their big boat and shared a smaller one with another family so that they could still enjoy sailing on the sea. They gave up the extra car and their professional wardrobes. They also gave up expensive hobbies. They seldom ate out, thereby reducing a lot of expenses. Now they no longer purchase things on impulse and only spend money on the bare necessities.One may think that they are too stingy toward themselves. But that is not the case. For them it is a voluntary act to have chosen this simple and frugal lifestyle. It is by no means deprivation. They believe that a frugal life is beneficial to both society and the individual.Theme-Related Writing▆Write a composition of no less than 150 words on the topic “Healthy Lifestyles”.
