When you have a choice between the easy and the difficult route, and you choose the difficult one, it is called foolishness or arrogance by the quick-guns, but the wise and perseverant call it courage or far-sightedness.
In the same way, when you know someone deserves to be punished and then you let them go, that is pure power. Nothing beats that kind of power. No king who followed the paths of Dharma alone was able to wield such power as those who used the same rules to instill respect in every heart.
Watching "Schindler's List" gave me the above idea, which has been sinking slowly into my mind for the past two days.
Also coming to my mind is an advice given by my father's elder brother when I visited him after I joined L&T. He said: "Those superiors who behave well with you even when you make mistakes are the best employees, and your best guides. Judge people by the way they treat subordinates". And I found that it is so far the best advice I received about corporate conduct. I have this rule carved in my mind: "Be strict about your work standards. But when others slip, don't curse them. Help them come to your level or go even higher. Also, never lose a chance to appreciate a good effort or to learn from someone more skilled than yourself."
And most importantly, never let the stress get to you. Do what you love and love what you do. The day you feel you are unable to do these, it is time to move on and try your luck elsewhere.
