Always, Always Run Short

If you have thirty minutes, take 25. If you have an hour, take 50. Always respect your audience’s time and end early. As a bonus, that forces you to hone your presentation – and to prepare to shift gears if your presentation takes an unexpected turn.
Finish early and ask if anyone has questions. Or invite them to see you after the presentation. But never run long… because all the good will you built up could be lost.
Watch Angela Lee Duckworth on the power of grit. Yes, grit.
