Destiny : An original poem

What's is life? Its not a destiny?
Born with you, brought up with expectation
Life between birth and death is simply gestation
Changes we want, changes we see
But changing something is upto destiny
Happy for sane, want always hapiness
But happiness and sadness is what he fixes
Cannot blame God for having met failure
For he is the maker and we are the sailor
Toil from birth throughout his life
But life is what we must always strive
What is life? Its not a destiny?
Work and work all the time
But at the end not even a penny!
