INPUT ARTICLE: 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.

SUMMARY: Recite your speech to yourself. Keep the speech brief. Speak with confidence.

INPUT ARTICLE: Article: Your body can more easily absorb and utilize natural forms of vitamin E. The synthetic version of vitamin E is called tocopherol acetate. This form may react with some beauty products, so it is best to choose a natural form of vitamin E oil, which you can find in a health food store, the vitamin aisle of a well-stocked grocery store, or online. Some food grade oils contain vitamin E as well, such as wheat germ oil, sunflower oil, and almond oil. Look on the packaging for d-alpha tocopherol, d-alpha tocopheryl acetate, or d-alpha tocopheryl succinate. Some people are sensitive to vitamin E oil, so it is a good idea to test a little on your skin before using it on your hair. You can also develop a sensitivity to vitamin E oil over time, so pay attention to how the skin on your scalp looks and feels after a few days of using vitamin E oil. To test the oil, apply 1-2 drops to the inside of your wrist and then massage it in. Wait 24 hours and then check your wrist to see how it looks. If there is any redness, dryness, itching or swelling, do not use the oil. If the area looks and feels normal, then you can use the oil. Vitamin E has been shown to be effective at promoting hair growth when taken as an oral supplement. Try taking two 50 mg capsules of vitamin E oil daily after eating a meal. For example, you could take one capsule after breakfast and the other one after dinner. As with any supplement, make sure that you check with your doctor first. Incorporate additional natural sources of vitamin E into your diet, too. Try nuts, seeds, green leafy vegetables, and plant oils, especially wheat germ and sunflower seed oil. You will get more vitamins from eating foods that are naturally high in vitamin E than taking a supplement. Vitamins E and C go well together because, in tandem, they are more effective at protecting hair and skin from damaging ultraviolet radiation. If you're taking topical vitamin E, you should take topical vitamin C. Similarly, if you take oral vitamin E, you should take oral vitamin C. These two will be more effective than either on their own.

SUMMARY: Choose a natural form of vitamin E oil. Test the oil on your skin before using. Consider taking a vitamin E supplement to promote hair growth. Consider adding vitamin C.

INPUT ARTICLE: Article: Student violins are usually made from less expensive woods and are manufactured by machines rather than by hand. These are less expensive, typically ranging from $100 to $800 and are perfect for beginners. If you are just starting to take violin lessons, you may not want to invest in an expensive and high quality violin only to discover that this is not the instrument for you. Once you have been playing the violin for a few years and want to improve the overall quality and sound of your instrument, you should upgrade to an intermediate level violin. Some brands will not produce an intermediate level violin, but those that do price them around $1,000. Professional violins are hand-crafted by a master luthier and are made from high quality wood. These instruments can cost thousands of dollars and are ideal for professional musicians or art collectors. Traditional acoustic violins create warm and rounded tones as a result of the natural resonance of the tonewood. These instruments are best suited for classical and folk music. It is possible to attach an amplifier to an acoustic violin. If you only need an amp for some songs, it is best to stick with an acoustic violin. Electric violins have built in pickups that amplify the sound and produce a brighter and more raw sound than the acoustic violin. This is preferred if you are playing rock or jazz music. Consider the type of music you like. If you listen to rock music, you may be more inclined to use an electric instrument that can create a rock sound. If you are just starting out with playing the violin, you may prefer renting prior to making an investment. In many instances, you can actually rent the violin to begin with and then eventually buy the violin. Your rent payments will go towards the purchase price.

SUMMARY:
Buy a student violin if you are a beginner. Select an intermediate violin for improved quality. Choose a professional violin if you are an advanced violinist. Buy an acoustic violin to play classical and folk music. Get an electric violin to play rock and jazz music. Inquire about a rent-to-buy program.
