The document provides 7 tips for preparing good presentation slides: 1. Know your goal and be clear about the purpose of the presentation. 2. Plan out your presentation by creating an outline and sketching details. 3. Avoid using stock templates and instead build your own theme to avoid boring slides. 4. Choose 1-3 fonts and stick to them for titles, body text, and bullet points. 5. Use images as imagery and quotes are more memorable than just words. 6. Limit each slide to one main point with 15 words or less to avoid distracting the audience. 7. Don't overload slides with too much text or design elements.
