speak and listen to yourself      

Explanation:

When preparing for your speech, you should speak and listen to yourself. When  preparing for your speech, it is necessary that you speak and listen to yourself, this is to ensure that your speech carries the necessary message, tone of voice and if it is orderly. This will also boost the confidence of the speaker as he/she will become confident of his/her own voice and improve the skills of the speaker.

The first draft of a speech does not always need to be fully fleshed out, that is why it is draft, it should contain the rough idea of what you want to speak on and then improve on it in subsequent drafts.

Lastly, the speech does not necessarily need to be written the way you would write a formal paper, that is dependent on your audience and what you are comfortable with. For some speakers, all they need are just bullet points to remind they of the key points of their speech.
