My best advice is to not start in PowerPoint. Presentation tools force you to think through information linearly, and you really need to start by thinking of the whole instead of the individual lines.
Your ability to shape your future depends on how well you communicate where you want to be when you get there. When ideas are communicated effectively, people follow and change.
Most presenters are consumed with preparing their content rapidly, which makes the material about their own narrow perspective.
The future isn't just a place you'll go. It's a place you will invent.
Phrases that have historical significance or become headlines don't just magically appear in the moment. They are mindfully planned.
