A speech is usually relatively short in time. But this doesn’t mean that you shouldn’t prepare for a short speech. In terms of preparation time, there may be also a lot of time involved to prepare for a short speech.
As there is not a lot of time you need to carefully consider what to say and what not to include in your speech. Therefore when you plan for a next speech and have influence on when this speech will occur you should plan it on a data that allows you for enough time to prepare. Preparing for what to say may take as long or longer for a short speech compared to a longer presentation. The number of times you can rehearse a short speech will obviously be more per hour compared to a longer presentation. Please note that the book that is part of the Public Speaking Kit comes with a separate booklet with tips and tricks for giving a speech. This booklet is available for download for a limited period of time.
