“An arrogant person considers himself perfect. This is the chief harm of arrogance. It interferes with a person’s main task in life—becoming a better person.”

Context: When he (Virat Kohli) fielded, he said something to me, and I said to myself, 'I'm going to show you you're not the only good batsman.' That's the way he is. He's very arrogant, he's very aggressive when he fields, and when he bats as well. He's just a very aggressive person. Those things motivate our players and it certainly motivated me. That really urged me to bat the way I did - to show him that he's not the only one who can do it. That played a big role.

1950s, Conquering Self-centeredness (1957)
Context: We never get anywhere in this world without the forces of history and individual persons in the background helping us to get there. If you have the privilege of a fine education, well, you have it because somebody made it possible. If you have the privilege to gain wealth and a bit of the world’s goods, well, you have it because somebody made it possible. So don’t boast, don’t be arrogant. You, at that moment, rise out of your self-centeredness to the type of living that makes you an integrated personality.
