1 follows the practical principle of 10: 1. For every hour of the course, you need to spend at least 10 hour to list the outline of the new course, do relevant research and design the exhibition plan. That is to say, a new eight-hour course takes up 80 ~ 100 hours of preparation time. So you should prepare at least one month in advance and rehearse several times before the formal course.

2. Plan a speech in less time than expected. Sometimes, what you think can be done in 10 minutes actually takes 20 minutes. For every 60 minutes of class or platform presentation, prepare 45-50 minutes of content materials, so that you can also have flexible time to tell stories, interact and answer questions.

3. Make more preparations to prevent some trainers from being too nervous when teaching, and it will soon be over. Write the estimated time node on your written materials as a reminder, do enough exercises and control the appropriate speed.

4. Meet the students. The lecture started before the speech and will continue after your speech. Before you introduce yourself, spend some time with the audience. In this way, it will be better to face familiar faces than complete strangers when giving lectures.

5. Shorten the activity time and allocate the collective activity time. If you think students need 20 minutes to do exercises and give them so much time, they will actually finish the exercises soon, and then use the rest of the time to reply to emails or make phone calls. Give students less time, and their seminars will be more tense and creative.

6. Take a break at least every 90 minutes. If the audience is sitting in a theater-style seat, take a break every 60 minutes. If they sit in the classroom seat, take a rest every 75 minutes. Never rest after 90 minutes. Adults' attention will weaken as the body feels tired.

7. Start on time after the break. If you tell the audience to come back after a five-minute break to continue the class, then you will inadvertently train them to come back after five minutes.

8. Finish on time, no matter how late you start, finish on time. Procrastination is disrespectful to students' next plan, and it will also disrupt your own plan. Calculate the length of your concluding remarks and practice how to jump directly from any part of the speech to the concluding remarks.

9. Print out the outline. If you are scheduled to speak for 60 minutes, and your previous speaker is 30 minutes overtime, then you'd better only speak for 30 minutes. Print out PPT outline. You can directly click on the page you want to show during the speech, otherwise the audience will think you are despised when they see you skip some PPT that you haven't said before.

10, don't rush out of the classroom. After the course, stay for a while and chat with the students. Many people have some questions that they don't want to ask in public, so they will ask you alone after class. Others will talk about their personal experiences according to a point you made, or thank you for your help in this speech. You won't have no time to listen to these contents.
