Method
How should I make this presentation?" What approach should you use? Formal or informal? Lots of visual aids or only a few? Will you include some anecdotes and humour for variety?

"What should I say?" Now you must decide exactly what you want to say. First, you should brainstorm your ideas. You will no doubt discover many ideas that you want to include in your presentation. But you must be selective. You should include only information that is relevant to your audience and your objective. You should exclude all other ideas. You also need to create a title for your presentation (if you have not already been given a title). The title will help you to focus on the subject. And you will prepare your visual aids, if you have decided to use them. But remember, in general, less is better than more (a little is better than a lot). You can always give additional information during the questions after the presentation.
