Subjecting yourself to vigourous training is more for the sake of forging a resolute spirit that can vanquish the self than it is for developing a strong body.
Mas OyamaIf you have confidence in your own words, aspirations, thoughts, and actions and do your very best, you will have no need to regret the outcome of what you do. Fear and trembling are lot of the person who, while stinting effort, hopes that everything will come out precisely as he wants.
