Just like your favorite show or movie. Start dropping bread crumbs regarding your main point right from the introduction. Tell a few mini stories that have a clear beginning and conclusion along the way. And within those mini stories leave 1-2 of those bread crumbs. By the time you’re right before the conclusion, you’ve planted more than enough crumbs out there for the audience to follow. Then at the conclusion when you tie it all together, the audience feels brought along the journey because they recall the breadcrumbs you left.
Work backwards from you point. Tell mini stories.
