The typical person speaks 10 or 12 sentences a minute.

The atomic method requires you to create a slide for each sentence. For a five minute talk, that’s 50 slides.

Each slide must have either a single word, a single image or a single idea.

Make all 50 slides. Force yourself to break each concept into the smallest possible atom. If it’s not worthy of a slide, don’t say it.

Once you have 50 slides, do the talk in practice. Remove slides and sentences that add no value or don’t move you forward.

Now (and only now), start consolidating slides. If two or three or four slides work together as one, then go ahead and make them one. You’ve got molecules now, not atoms.

At this point, you can either get rid of slides altogether, keep them as is or lump them one more time into bigger ideas. But no (!) bullets please. What a waste those are.
