I am motivated to work hard today.

The order is backwards in most people's heads. Motivation gets treated as the fuel you need before starting, when it behaves far more like exhaust — a thing the engine produces once it is already running.

Which is why the first ten minutes are so disproportionately awful, and why they are also the whole of the problem.

Nobody feels like writing the report. People who write reports have simply learned not to consult themselves about it first.

Open the file. Do one paragraph badly. The wanting tends to turn up around minute seven, having missed the start entirely.
