It's best to have a plan for how you will introduce yourself so you don't get lost or confused when you're on stage. It's even better if you can write your plan down so you can review it beforehand or refer to it during your presentation. You can write down every sentence if you'd like, especially for practicing the introduction. When it's time to present, it's probably best to just write down a few notes or key words to remind you of what you want to say so you don't just read off your note cards. Practicing your introduction out loud will help you speak with the right intonation and at the right pace so your message will be clear and interesting. You can also time yourself and add or remove certain parts of your introduction until you've got it just right. Ask your friend for constructive feedback and advice on how to improve. Practicing out loud will also help you gain confidence. If you don't have a friend to watch your presentation, record yourself on video and play it back later to refine your presentation skills. It can be uncomfortable to watch yourself on video, but it will help you nail your introduction. You can even record your whole presentation. Keep recording and re-recording until you are happy with it. Then you know the audience will be happy too. You will want to make a good first impression with your introduction, so be sure you know what is expected of you and what might be frowned upon. Research the local culture where you will be speaking: what do they normally wear in the industry there? Do they introduce themselves by first name only, or with their first and last name? Be mindful of international customs too. In some places, it's not appropriate to use humor. If you are unsure about your audience, leave the humor out. The best resource to learn about the local culture is the locals themselves. If you have a contact where you will be speaking, ask them about customs, dress code, and how humor is usually received. If you don't know anyone personally, try searching in industry-specific online forums. Find YouTube videos of presentations given in the area that are relevant to your industry.

Article: Before you begin cleaning a sticky keyboard you will need to shut down your computer. Once your computer is shut down, make sure its power sources are disconnected. For example, if your desktop is plugged into an outlet, you will need to unplug it. If you are using a desktop computer you might have a keyboard that connects to the computer through a USB or PS/2 port. If this is the case, you will need to unplug the keyboard from the USB or PS/2 port prior to cleaning. Tilt the keyboard upside down. Use your hands to gently shake out any loose debris. You should not attempt to shake loose debris from a laptop keyboard. The shaking could potentially damage the computer. If you have a laptop computer, or if there is residual debris in a standard keyboard that cannot be removed by shaking, you should use a can of compressed air. Spray the compressed air in between the keys and in all the keyboard's crevices to remove loose debris.
Question: What is a summary of what this article is about?

Article: Cut it in half, loosen the segments, and eat it straight out of the peel with a spoon. When you cut the ugli fruit open, the inside should look similar to that of an orange, but the fruit should appear slightly fleshier than an orange would. Unlike grapefruit, the ugli fruit is sweet enough on its own and does not need any added sugar. If you do add sugar to the fruit, you may even find it too sweet. An ugli fruit can be enjoyed in this manner as a simple, light breakfast. If you want to use the fruit for a light yet exotic lunch or dessert, you can cut it in half and drizzle it with a bit of sherry or kirsch before enjoying it. Peel the skin off the ugli fruit and separate it into sections, like you might expect to do with a tangerine. The segments can be eaten one by one. The skin is thick yet loose and puffy, so you should be able to remove it with your fingers. There are seldom any seeds, so you should not have to worry about removing seeds before enjoying the fruit. The segments inside the fruit are also easy to separate, and you should be able to separate those with your fingers, as well. Enjoy the fruit in this manner as a snack or side dish to your breakfast, lunch, or dinner.

Eat the ugli fruit with a spoon. Peel and separate the segments.
