Before a speech, your heart is pounding. The audience sees way less of it than you feel.

Nerves are almost entirely interior. The pounding, the dry mouth and the shaking hands are vivid from inside and nearly invisible from six rows back, where people see somebody standing up and talking. Assuming your fear is on display makes you apologise for it, and that apology is the only part the room actually notices. The gap between how it feels and how it looks runs reliably in your favour.

Before the next one, let your hands shake without remarking on it. Take one slow breath before your first sentence instead of rushing to start. Afterwards, ask somebody whether they could tell.
