Courtesy should be apparent in all our actions and words and in all aspects of daily life. But be courtesy, I do not mean rigid, cold formality. Courtesy in the truest sense is selfless concern for the welfare and physical and mental comfort of the other person.
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.
Mas Oyama
