Leaked from BoJo's draft memoirs?
Some fool lectured to me once, listing the four chief virtues as Wisdom, Justice, Fortitude and Temperance. As I heard this I knew I had none of them. But I have other virtues. Ambition, that can be a virtue when it drives us to excel. Resourcefulness, where I will miss no opportunity to advance my own interests. Courage. Perhaps not physical courage, but there are many forms of courage. Devotion, to myself and those who have sworn loyalty to me. But none of my virtues were on his list, which is why that other person is a fool and I am now Prime Minister.
