Professional speaker Ron Hoff suggests you consider when you pick a subject to talk about:
- Startling or thought-provoking - be careful not to have one so startling you offend your audience
- From your journal - pull something out of the journal you keep on story subjects
- Gets you thinking visually - find a subject that gets you thinking of particular images and makes your mind make visuals about it
- Suggested by the person who invited you to speak - customize the subject to make it yours
