Spirituality does two things for you. One, you are forced to become more selfless, two, you trust to providence. The opposite of a spiritual man is a materialist. If I was a materialist I would be making lots of money doing endorsements, doing cricket commentary. I have no interest in that.
I don't care if people I admire criticize me because their opinion is valuable to me.
Leadership must be likeable, affable, cordial, and above all emotional. The fashion of authoritarian leadership is gone. Football is about life. You can't be angry all day.
