It is a highly open world now. It is a fully interacted world now. It is an abundant world now. So, with the rapid development of the global economy and culture, our life has also entirely changed. Our spare time have been no longer mono and boring with only few entertainment activities, and there are many activities nowadays instead. It is because the changes in the abandance of life that the question of a meaningful life generates. It is said that the greatest use of life is to spend it for something that will outlast it. Thus, what is the content of a meaningful life on earth? It is usually said that a meaning life, in common sense, is that one can achieve what he or she wants, except the harmful such as criminals or anti-social activities. Some people are extremely fond of sports, no matter the greatest professional tennis player Roger Federer or an ordinary person who love a certain sport. In regardless of whether can his or her hobbies can bring financial or substantial interests, he or she will reach a concensus that it is great to do his or her hobbies and procceed to a higher level of the fields of his or her hobbies. Once, the Swiss professional tennis player Roger Federer was interviewed by a reporter. He said that tennis was a fraction of his DNA and he will continue to play tennis until he can no longer play tennis caused by unresistable factors. In my opinion, a meaningful life should not be judged by others' opinions, but we should set a definition of our own meaningful lives instead. Taking myself as an example, so much do I love tennis that I will play tennis once I am free, and even feel very uncomfortable if I have not played tennis for a long time. So, it will be a meaningful life that I can get more and more progress in tennis especially the techniques of tennis, no matter I can earn money through it or it is one of my sheer hobbies. Only when I get to higher levels can I make my life meaningful.
