There is always olny one Ram, One Krishna, One Gandhi, One Tendulkar and one bachchan. Why? because all these invested their whole life to become what they would be. Others just spend their life in what they wanted to be. There is a minor difference between these two sentences. Once the great painter Picasso was wondering in street when a young lady identified her. She asked him if he can prepare a nice sketch of her immediately. Picasso happily created a nice painting of the lady just in few minutes on the road. The lady extremely impressed and said I would have spent my full life to develop this picture. Picasso replied. Madam I have already spent my full life to develop this.
Hope you understood now why there is always only one Ram, one Krishna, one Gandhi, one Tendulkar and one Bachchan.
