Problem: Article: White shirt collars tend to pick up built-up dirt, oils, and haircare products from the back of your neck, leading to grungy, yellowish discoloration. The next time you plan to put on a white shirt, jump in the shower first and give the back of your neck a good scrub with soap or body wash. If you don’t have time for a shower, wash the back of your neck with a soapy washcloth or a cleansing wipe before putting on your shirt. If you tend to use hair products (such as gel or wax) or skincare products (like lotions or moisturizers), wipe the back of your neck before putting your shirt on. These products can easily pick up dirt and grime, and some may contain staining ingredients. Let any hair product dry before putting on your shirt, especially if your hair is long enough to touch your collar. The major culprit behind those aggravating yellow underarm stains is not your sweat, but the aluminum used in many deodorants and antiperspirants. A chemical reaction between sweat and aluminum creates the yellow discoloration. To prevent this problem, switch to a natural, aluminum-free deodorant that focuses on combating bacterial odors rather than blocking your pores.  Look for deodorants that say “aluminum free” on the label, or make your own deodorant using household ingredients and essential oils. Some antiperspirants are formulated to both reduce sweating and prevent yellow stains. Look for deodorants that say something like “anti-yellow staining” or “fights stains on shirts” on the label. To fight wetness without shirt-staining aluminum, combine an aluminum-free deodorant with a sprinkling of absorbent Gold Bond or a little baby powder. Undershirts provide a barrier of protection between your shirt and your body. They may be particularly useful for preventing underarm stains. If you perspire a lot, look for undershirts with built-in sweat guards. Having a lot of armpit hair promotes excess sweating, especially when the weather is hot. Protect your shirts from sweat stains and reduce your need for staining antiperspirants by removing some or all of your underarm hair. Catching and treating stains early is key to preventing them from taking hold. As soon as you notice discoloration starting to develop on your shirt’s collar or underarms, use a commercial pre-laundry stain treatment on the area. Wash or dry clean your shirt as soon as possible. Enzyme-based cleaners are especially good for tackling sweat stains.
Summary: Wash your neck thoroughly before putting on a white shirt. Wipe excess hair and skin products off your neck. Switch to aluminum-free deodorant to prevent pit stains. Wear an undershirt to protect your shirt from sweat. Trim or shave your underarm hair to reduce sweating. Wash white shirts immediately after wearing them.

Problem: Article: Many students think that it isn't important to start doing your best until your first year in high school, but this is far from the truth. If you want to start off your freshman year with Honors classes, you have to make As (or high Bs) in your 8th grade year; otherwise you likely won't get accepted into these competitive, impressive, and highly sought after Honors classes. Every school is a bit different. Some schools require tests to be admitted to Honors classes, some take students based on teacher recommendation, while others will put you in whatever classes you feel like taking. To make sure you can start out high school ahead of the curve, it's best to be impressive during your years in junior high, too. If you want to excel in extracurriculars in high school – which is a great way to get scholarships, attract attention to colleges in general, and show you're well-rounded – you need to start now. There will be some really good athletes and performers in your high school, so keep up with them by starting early.  Experiment with a few activities while you're still young enough to drop them if you don't like them and pick another. And don't just stick to one area – if you're big into sports, branch out to dancing or a musical instrument. If you're more artistic, find something athletic to give a try. You could be great at it! Read the class descriptions and talk to other students who have taken the classes you're interested in. Taking a class just because a friend is taking it too won't help you and, what's more, your friend will probably just be a distraction. Instead, look for classes with students and material that is slightly above your level as the best motivator is competition.  If you're looking to be valedictorian, one of the ways to cinch that is to take loads of Honors classes (provided you can still get As). Straight As in Honors classes are even more impressive than straight As in regular classes, so take as many difficult classes as you can handle – without compromising your GPA, of course. A great GPA in normal classes is better than a poor GPA in Honors. Keep in mind the subjects necessary to pursue your intended career. If you're considering becoming a psychologist, for example, take psychology and sociology over Metal Shop and Ceramics. If you can, look at the textbooks for the various classes. Oftentimes the rigor of the textbook will reflect that of the class. Ask your teacher or office staff if you can get the textbooks during the summer – most schools have last year's textbooks in a closet somewhere just waiting to be read. Unless the books are new and they're being shipped, there's no reason you shouldn't be able to get yours to read for the summer.  Ask your teachers, older students or consult the Internet to find the best sources for supplemental readings. Use several reference books that will augment your understanding of the material. This way you'll be able to truly wrap your brain around any concept your teacher presents you. Don't be afraid of seemingly difficult material. Think of it as a challenge and face it head on. It may be confusing now, but when your class is covering it, it will all click into place and you'll be that much further ahead.
Summary: Make the best grades you possibly can in your 7th and 8th grade years. Start your extracurriculars now. Pick the classes you enroll in carefully. Obtain the textbooks early, and supplemental ones, too.

Problem: Article: It's easier to see the dust and dirt when the monitor is off, and safer for you and your computer.  Make sure that you let the screen cool down before you start if you're cleaning a plasma TV. If you try to clean the monitor while the pixels are firing you may end up damaging the screen. While the risk is small, there is the possibility of an electric shock if you clean the monitor while it’s on. These can easily damage your screen, especially if it has a matte, anti-glare finish.  If necessary, use distilled water. No tap water since it can leave mineral deposits on the screen. Make sure that your microfiber cloth is just barely damp. Consider buying a specifically formulated screen cleaning fluid. Read reviews and check your users manual to make sure which are safe for your particular monitor. For a mild homemade cleaner, mix water and white vinegar in equal proportions. Use this to dampen (not wet) your cleaning cloth.  Always apply any liquid to the cloth, not directly to the screen, to prevent dripping (if even one drip reaches the bezel, it will immediately ruin your monitor). Don’t use anything soapy that can leave a residue. These are convenient and specifically designed for monitors.  Make sure they are gentle enough for anti-glare screens, if you have one. Read reviews online or ask a salesperson to find a good brand. This prevents any moisture that may have gotten into your monitor from causing damage, or electrical shock.
Summary:
Turn off and unplug the monitor. Do not use ammonia, alcohol or acetone-based products. Consider using screen wipes. Make sure everything is dry before turning on your monitor.
