The meaning of life lies not in the length, but in the connotation. Everyone can make his life more valuable through his own efforts. The existence of life is worthy of recognition and respect. If we can do our best to make more contributions to others and society, such a life will be more valuable and worthy of respect. To enhance the value of life, we need to be down-to-earth, starting from now, starting from me and starting from small things. We should set up lofty ideals, study hard, master skills, repay the society and benefit mankind when we grow up, and let our limited life have unlimited connotation.
