Quote from Stephen Richards * The only time when you fail is when you fall down and stay down *

Tenacity. Doggedness. Determination. Do you have any of these traits  in you ? . This is the question achievers ask themselves many times. Their firmness keeps them on the winning track in spite of the odds stacked against them many times. The tough gets going when the going gets tough. The achievers make their own destiny and take all adversities in their stride. Stephen Hawking has a motor neuron disease   which has worsened over the years. Stephen got this when he was in his early twenties and aspiring to become a top notch scientist.   Initially Stephen lost his ability to write , however he developed visual methods including seeing equations in terms of geometry.
