When I create a presentation, I tend to rely more on weaving a story. Something that will keep people interested. I have to think through imagery, and pictures and give people something that will add to my words.
When I start writing an essay, I tend to make a lot of statements, and truths, backed up by numbers and anecdotes, but less spun into a story. I’m not thinking much about imagery.
It pays dividends to do both for any topic you’re serious about making in impact in. From their you have a coherent story, dotted with facts, figures, and anecdotes to back it up.
It’s a powerful combination.
If you’re stuck, try creating for a different format.
