How to Pick the Right Topic - Keeping Things Simple

When selecting a topic, always try to keep things simple. For instance, let’s say your talk aims to answer an important academic or business question. Instead of stating the longest or most complicated form of that question, instead attempt to revise that question repeatedly until it is as simple and concise as it can be without losing a lot of its content. In short, make your question as clear and as obvious as possible.

This also holds true with other types of speeches. The more you try to work into your speech, the weaker, broader, and less coherent the speech will appear. Instead of trying to cover so much, focus on picking a small slice of content to cover—and then to cover that slice well.
