If you're about to go on stage as a speaker, remember that the audience wants you to succeed and they've come to learn something. Before your talk, double-check the agenda and room setup, be there 15 minutes early, and familiarize yourself with the technical equipment. On stage, take deep breaths, start with a strong opening, practice your pace, use pauses for emphasis, and don't be afraid to make mistakes - just roll with it. During Q&A, prepare by anticipating common questions, include the audience in answering questions, and if you're unsure, ask them to reframe or repeat the question. After the talk, reflect on what went well and areas for improvement, and use this experience to improve future talks.
