From the Green Room: Right before you get up to speak, try not to focus on the broader significance of what you are about to do (e.g. my career depends on this, I have worked so hard to get to this moment). Instead focus on something one technical reminder. (e.g. Breathe. Keep feet planted. Smile.)
