The life span of rainbow is not as long as that of stone bridge, and stone bridge is not as beautiful as rainbow. However, the stone bridge is not beautiful, but it has been firmly placed on both sides for a long time, communicating with each other silently, which is the value of its life; The existence of the rainbow is only a moment after the rain clears, but its instantaneous beauty has left a permanent memory, which is also the value of life.

As petofi said: "The amount of life is calculated by time, and the value of life is calculated by contribution." Life is limited, the road of life is only a few decades, and we can't extend it indefinitely, nor can we seek its eternity. But we can pursue beauty and give everything to ourselves, but decades of silent dedication can be exchanged for eternity; A magnificent feat, a moment of beautiful display, can also be said to be the eternity of life. Therefore, the value of life is not life itself, but dedication. As long as you make a contribution, whether it is a long-term unknown contribution or a short-term brilliant glory, such a life is eternal.

Paul's famous saying

"The most precious thing is life. Life only belongs to people once. A man's life should be spent like this: when he looks back on the past, he will not regret wasting his time, nor will he be ashamed of doing nothing. In this way, when he dies, he can say, "I have devoted all my life and energy to the most magnificent cause in the world-the struggle for the liberation of all mankind." "
