The riches in the world are not found in the famous gold and diamond mines,where many men and women are digging for them.Most riches in the world are found in the cemeteries(墓地)and grave yards,buried with people’s dreams,aspirations,and unfulfilled potential.Why is it so?

Countless men and women died without ever having the courage to follow their own paths.Maybe because they were afraid to violate some kinds of social norms, maybe because they were afraid to be alone,or maybe simply because they preferred to settle for the familiar.They went to the graves,with a song that would never be heard,a piece of poetry never be written, a dance step never be initiated and a heart full of dreams and aspirations,leaving behind a life full of potential yet no legacy.

Michael Jordan,one of the greatest athletes once said,‘‘I can fail,but I cannot afford not to try.” Life remains a beautiful journey if we learn to take that step and to work that path.Every challenge and defeat in the process becomes a light post that sharpens the vision and shapes the direction forward.

“In my world nothing goes wrong,”said the great Indian sage Nmaja Dhahta Majraj.We must learn to trust the greatness within all of us and know that each of as is here to bring our unique contribution to the universal monument.If each of us learns to dance to the music we only can hear, society as a whole will evolve naturally and spiritually toward love,peace and happiness,and will be void of jealousy,envy and discrimination.

And Henry David Thoreau would say, “If a man does not keep pace with his companions,that is because he hears a difierent drum.’’And one truly believes that the path to success and happiness passes through the dancing to such a unique drumbeat.Therefore,do not die with the music still playing inside you.
