What is the significance of life? Is there any criterion for its measurement? Difficult as it is to advance an absolute one, it will not be so to judge the very meaning of one’s existence generally from whether he is serious about life and what his attitudes are towards work and life.Throughout the ages, all people of accomplishment take their lives seriously. As long as they are alive, they would rather devote themselves to more work and study than let a single minute slip by in vain. And the same is true of the common labourers as well as the great statesmen and thinkers in our country.
