Summarize the following:
Do not make his being wrong about his intelligence or other aspect of his character. This will be more likely to put him on the defensive; if you isolate his specific action or thought (whatever he is wrong about) from his character, he will more easily see the err of his ways as his identity and self-esteem is not so wrapped up in the exchange. For example, rather than saying something that makes a character judgment like "you've definitely not been paying attention or there is something wrong with your memory because I did the dishes last" say something that focuses more precisely on the specific wrongness, like "I believe you're actually wrong about who did the dishes last time." People will be more inclined to believe you that they are wrong if you offer an alternative that is right. If you just point out that they are wrong but do not follow up beyond that, without any alternative, they will be more likely to stick to their guns. Speak with authority but also remain modest in your conversation. Again, the main idea here is that you do not want him to get on the defensive. Do not be aggressive, let him know softly by saying something like "I think you may be mistaken here" rather than "you are absolutely dead wrong on that"; the former is more abrasive and will more likely lead to an automatic aggressive response by him, such as refusing to take your position seriously. The angrier or more exasperated you seem, the more power he will have. Stay calm and if he just won't accept the facts, consider walking away. It's often not worth a fight to prove someone wrong. Be comfortable knowing that you are right and that in some cases it doesn't matter what anyone else thinks. Try sandwiching his being wrong between two positive qualities about him, or weaving in other things he was right about. With this technique, he may not feel too negatively about your correcting his being wrong. Take an example where your roommate is wrong about his belief that he did the dishes last, and it is a frequent enough occurrence that you decide to bring it up. You might say something along the lines of "When you do the dishes they always come out nice and clean but I think you're wrong that you did them last. I remember doing them yesterday while you were playing that sweet song on the guitar. Do you remember that?" Be sure to drive home the point that the real reason for the conversation is to let him know that he was wrong about something. Do not spend too much of the conversation on what he did well, otherwise he may focus too much on that or not get the take home message you intend to leave him with; this will undermine the use of the sandwich technique. However, avoid being condescending, too. It is a fine line to walk; you will be less likely to be perceived as being condescending if the 'bread' layers of your sandwich are genuine.

summary: Point to behavior, not character. Show how to be right. Ease him into it. Don't get worked up. Try the sandwich technique.

Summarize the following:
Its always important to greet your clients in a friendly way. Even if you continue what you are doing before helping them, its important to greet them so that they feel acknowledged and know that you will help them in a moment. Some greetings are "Hi! Welcome to [Business name]" or "Good morning! If you'll have a seat, I will be with you in just a moment!" Be respectful. Treat everyone like they are the most important person that has walked into the office that day. This is your job- nobody cares about how you got stuck in traffic this morning, how you ruined your brand new purse, or even how you lost your favorite CD. Leave personal matters at home. (Even if you don't respect their message or the way they convey it- fake it) Overall, make sure the person is totally relaxed and happy to talk to you. You are representing a business, thus you should dress the part. Invest in some business casual clothes. Alternatively, if you are a receptionist at a specific sort of store (such as a clothing store) you may consider dressing the part by buying some of the store's clothing and wearing them. Tend to the conservative, unless you work somewhere where fashion, trendiness, or other factors are pushed to the forefront. Check to see if your business has a specific dress code. Your business may be fine with casual dress, just remember that you should never dress too casually (sweats should be banned from the workplace.)

summary: Have a greeting ready. Be courteous. Dress to impress.

Summarize the following:
If you find that you have too much energy during the day, you may be consuming some form of a stimulant. Try to reduce your coffee intake. This is the most popular stimulant used by adults. You may think that you need your morning coffee in order to power through the day. Chances are, if you feel really hyper throughout the day, you may be overloading. Try cutting back on your coffee. Go from 3 to 2 cups a day and see if there is a change. If you are more of a tea drinker, do the same for tea. Caffeinated sodas can also be the culprit. Reduce the amount of soda you drink in a day. Drink water instead. Eat less chocolate. Just like with coffees, teas, and sodas, chocolate won't necessarily lead to hyperactivity, but it can certainly give you a rush of energy that may be interpreted as such. The primary concern with sugars is that they get into your bloodstream quickly. So if you eat a lot of sugary foods, you are constantly feeding your body a source of quick-burning energy. If you normally get really hyper after lunch, reduce the amount of sugar you take in at lunch. See if this helps. Many parents and medical practitioners agree that lab created colors and additives may lead to slightly higher levels of hyperactivity in children. There is no definitive study that points to artificial coloring or additives as a cause of hyperactivity. Studies that do exist rely on subjective findings, in part, because they have to rely on parents to describe the changes in their own children. Other opponents point to the fact that most food items with artificial ingredients are also loaded down with sugar. The stimulant sugar may be the cause of the increased hyperactivity. Eat a lot of fish, like salmon and tuna. Many leafy green vegetables also contain fatty acids. These fatty acids facilitate the transfer of neurotransmitters in the brain. When your neurotransmitters function improperly, it can cause hyperactivity and loss of concentration. Oftentimes, omega-3 fatty acid deficiency and ADHD are mistaken for one another. Since your body cannot create these fatty acids, it is necessary for you to include them in your diet. Since nicotine is a stimulant, you may be getting an unneeded energy boost during your smoke breaks. Try skipping cigarette breaks at points in the day when you might otherwise feel hyper. If the above steps don't help to alleviate hyperactivity, see a nutritionist. They can examine your particular diet and then suggest specific alterations to help your hyperactivity, energy crises.
summary: Avoid stimulants like caffeine. Eat fewer sugary foods. Eat foods without artificial coloring and additives. Consume foods high in omega-3 fatty acids. Stop smoking. Talk to a nutritionist.
