If you don’t have time to make good slides, don’t make any.
Most presentations would be better without slides. Because most slides compete against the presenter instead of supporting them. I know what it’s like. A presentation is looming and you leave it late to create slides. And when you do finally open PowerPoint you do the obvious thing: you create slide after slide of bullet points. If you’re short on time, skip the slides. Those rushed slides are bad slides. They are bullet-heavy, text-dense, and hard to follow.
