Few is more. Presenting is like writing an executive summary. Get the points quickly
Imagine that you had 30 seconds instead of 30 minutes at the next executive staff meeting to get your message across. Would you be able to focus your energy on the most compelling way to convey your most important thought?
When you prepare a presentation, work backwards. Start with the key message or takeaway that you want to convey. Then imagine that you had to send that message via Twitter instead of using slides, charts, documents, and discussions. Force yourself to summarize your key points in no more than 140 characters. Based on that focus, then think through what other information you’ll need as backup and support.
Practice making your presentation without any slides or other supporting materials — and limit the time to six minutes. Think of it as a TED talk that’s going be watched by millions of people on YouTube.
