I made three gigantic mistakes in my political career. Not just the usual stupid things that politicians do, like wasting money on the NBN, but three extra special, deluxe model, monumentally unforgiveable blunders. I will tell you what they were, in the hope that even at this late hour I might find absolution for my sins, and so that you can derive some appreciation of the full horror of my tragic mistakes and the overwhelming sense of guilt that still wracks my body when I think of them.
