What is a one-sentence summary of the following article?
Writing a speech is only one aspect of the entire presentation. You also need to practice the speech out loud. That’s because often, the way that you write things might not actually roll off the tongue easily.  Go over any parts that seem confusing or that don’t flow easily. Make any notes or changes that will be helpful when delivering the speech. Time the speech when you recite it. Give the speech to a mirror so that you can see how often you’re able to look up from your paper without stumbling. You can also practice the speech in front of a close friend and ask for feedback. You might have a lot to say, depending on your tenure at this place and how much it has meant to you. However, this speech is not the time to go into minute detail about it. Remember that people likely need to get back to work, or have other things they’d like to be doing with their time. If you do it right, you can make a powerful speech in a short period of time. A farewell speech should usually be about five minutes long. Ten minutes is acceptable in certain circumstances. More than that should be reserved for extremely special circumstances, such as when a head of state resigns. Many people get nervous when speaking in front of a crowd. There are plenty of tricks to help yourself battle nerves if you need to. Make sure to practice your speech many times; then, prepare yourself for standing in front of a group.  Know that you may make a mistake. Be prepared for this. Don't beat yourself up if it happens. Acknowledge it and move on. You can even laugh at yourself to help put the audience at ease. Focus on people who seem to connect to your speech. If they're nodding, smiling, or have their eyes glued to you, focus on them. Their energy will help give you confidence.
Recite your speech to yourself. Keep the speech brief. Speak with confidence.
