If you want to win, but think you can't, It's almost a cinch you won't.
If you think you'll lose, you're lost;
For out in the world we find Success begins with a fellow's will;
It's all in the state of the mind.
Life's battles don't always go To the stronger and faster man,
But sooner or later the man who wins Is the man who thinks he can.
- Walter D. Wintle.
A great mathematician was living in a village outside Ujjain . He was often called by the local king to advice on matters related to the economy. His reputation had spread as far as Taxila in the North and Kanchi in the South. So it hurt him very much when the village headman told him, "You may be a great mathematician who advises the king on economic matters but your son does not know the value of gold or silver."
