Simple living doesn’t mean that you give up your job and start living in the countryside, but it means that we spend our time, energy and efforts on important things in life. It can be good for us in some ways.

Firstly, simple living can keep your mind peaceful. It makes sure that unnecessary things are out of your life and you concentrate on the real factors that affect the quality of life. Through simple living you can see the positive side of life and won’t feel jealous and greedy.

Secondly, simple living can make you have time for your loved ones. Most of us become so busy in our lives that we forget to spend time with our dear ones. People who believe in simple living value the time spent with their loved ones.

Thirdly, simple living is helpful in the improvement of health. By choosing to be simple, you feel less stressed in daily life. Simple living gives you a new view on things and helps you join in creative activities. It allows you to devote some time to recreational activities(娱乐活动), physical exercises, etc., which help you in leading a healthy lifestyle.

Fourthly, living simply allows you to have time to look back on the precious moments in your life. It makes you aware of your strengths and weaknesses. People who aimlessly pursue materialistic pleasure (物质享受)are often not sure what they exactly want from life. They never have time to analyze themselves. Simple living helps you stay happy with what life has offered you and helps in creating positives in your life.

Lastly, simple living can reduce your expenses. It can make sure that you’re doing your bit for the protection of the environment. If all of us reduce our daily expenses on electricity, fuels, etc, we’ll be able to stop the degradation (退化)of the environment.
