When you start preparing content for your next presentation you can use PowerPoint for this. Create a presentation in PowerPoint and start doing research. Put in text on pages, group pages per topic. Do a Google search and put images on pages that you like and are related to the topics. Search for relevant quotes and put these on slides.
At the beginning it is not necessary yet to do a careful analysis of what to put on a page. Just move forward by gathering information and put these on slides (including links to articles, video material, blog post). Create a broad collection, and move forward quickly. It is easier to delete stuff afterwards then to add more. If there are parts lacking in the content you can always go back to add more information. Now you have a PowerPoint presentation after your initial research phase that is filled with content and ideas. You can use this as a basis to further craft the story, select what is of real importance and delete what is not relevant for your presentation. By using MS PowerPoint you can craft your story for your next presentation. And remember for this phase: “Don’t let perfection get in the way of good enough”.
