To highlight, use connectors: “The key point here is…”, “What really matters is…” or “I’d like to emphasize that…”.
To organize ideas: “First of all…”, “On top of that…”, “Finally…”. Structure helps your audience follow along.
To close strong: “The bottom line is…” or “To sum up…”. End by making clear what you want to stick.
In practice
Highlight“This is the most important part.”
Sequence“First… second… and finally…”
Conclude“The bottom line is that we need to act now.”
