Think about what needs to happen well ahead of time.
Work out how long you need – make a timeline.
Look again – allow plenty of time for each step, and time for transitions between steps.
Add a bit for the unexpected… and a bit more.
Act as if you’re short of time – maintain a sense of urgency.
Don’t stop until you’re finished (early?).
