There's two kinds of rock n' roll casualty: the one that has huge success and adoration, and then suddenly it stops. Or there's when you're in a band: it is all-consuming, so then you have the dream of that, and then the dream's taken away from you even before it happens.

Proving yourself in a field where the casualty rate is so notoriously high is an ongoing challenge.

Regular order - the set of rules, norms and traditions designed to ensure a fair and transparent process - was the first casualty. The results: No serious deliberation. No meaningful oversight of the executive. A culture of corruption.
