I think the real reason for my improvement is because I had such a long period in the off-season just working as hard as I could on all my new dives; making sure I did lots of repetition to get them consistent.
One of the things I like about performing on the stage is that it is a kind of meditative experience. Time does stand still. You have no concept or feeling of the passing of two or three hours' time. It's all kind of one present moment, which is a kind of a description of meditation.
I had no difficulty as Secretary of Defense moving from the Bush administration to the Obama administration.
