All great souls lived less than an average human beings. Sankara 32, Jesus 39, Ramakrishna Paramahansa 52, Vivekananda 39 and so in. Their accomplishments are unbelievable leaving a trace for thousands of years.
Hence it is not important 'how long we live; but how we live makes the difference'. Few difference between great souls and common man is:
@ Common man grumbles all the time, great souls celebrate every moment.
@ Common lives only in the past and worries unknown future, great souls lives in the 'present' moment.
@ Common man thinks that the world is created for his indulgence, great souls think he is created to make the world a better place.
@ Common man dies without a trace and great souls live for ever.
Whole of my heart
