When consumers are offered a bonus gift for purchasing a product (target product), the perceived value and desirability of the bonus gift as a standalone product can sharply decline. To ensure that your offer is seen as the valuable proposition it actually is, the customer needs to be shown the true value of your offer.
When too many options are made available, consumers often find the decision making process frustrating, due to burden of having to differentiate options from one another to make best decision.
People who deviate from the average tend to be drawn to the average. They change their actions to be more in line with the norm regardless of whether they were previosly behaving in a socially desirable/ undesirable way. We should convey our approval/ appreciation of those already acting in socially desirable way. 
Focusing the audience on people who engage in positive behaviour.
People are motivated to follow other people behaviour that most closely matched our own environment, situation/ circumstances.
When people are uncertain about a course of action, they tend to look outside themselves and to other people around them to guide their decisions/ actions.
The last move to make before leaving for the party - even after you've given yourself final approval in the mirror - is to turn on the radio news/ scan your newspaper. Anything that happened today is good material. Knowing the big deal news of the moment is also a defensive move that rescues you from putting your foot in your mouth by asking what everybody's talking about. 
Never be left speechless again. Like a parrot, simply repeat the last few words your conversation partner says. That puts the ball right back in his/ her court, and then all you need to do is listen.
When you meet someone, imagine a giant revolving spotlight between you. When you're talking, the spotlight is on you. When the new person is speaking, it's shining on him/ her.
When talking with anyone, keep your ears open and like a good detective, listen for clues. Be on the lookout for his/ her preferred topic. If two people have something in common, when the shared interest comes up, they jump on it naturally.
When introducing people, don't throw out an unbaited hook and stand there grinning like a big clam, leaving the newlymets to flutter their fins and fish for a topic.
When asked the inevitable "And what do you do? You may answer "I'm an attorney".
Whenever you go to a gathering, wear or carry something unusual to give people who find you the delightful stranger across the crowded room an excuse to approach.
Rehearse being the Super Somebody you want to be ahead of time.
Whenever your conversation really counts, let your nose itch, your ear tingle, or your foot prickles. Do not fidget, twitch, wiggle, squirm or stratch. And above all, keep your paws away from your puss. Hand motions near your face and all fidgeting can give your listener the gut feeling you're fibbing.
When meeting someone, imagine he/ she is an old friend. You have reunited with your long-long old friend. The joyful experience starts a remarkable chain reaction in your body from the subconscious softening of your eyebrows to the positioning of your toes and everything in between.
The instances the two of you are introduced, reward your new acquaintance. Give the warm smile, the total-body turn, and the undivided attention you would give a baby who crawled up to your feet, turned a precious face up to yours, and beamed a big toothless grin. It shows "I think you are very, very special".
Before walking through any door - the door to your office, a party, a meeting, even your kitchen - picture a leather bit hanging by a cable from the frame. As you pass through the door, throw your head back and chomp on the imaginary dental gri that first pulls your cheeks back into a smile and then lifts you up. As you ascend high above the gasping crowd, your body is stretched into perfect alignment - head high, shoulders back, torso out of hip, feet weight-less.
This brazen technique packs a powerful punch. Watch your target person even when someone else is talking. No matter who is speaking, keep looking at the man/ woman you want to impact.
Pretend your eyes are glued to your conversation partners' with sticky warm taffy. Don't break eye contact even after he/ she has finished speaking. When you must look away, do it ever so slowly, reluctantly, stretching the goey taffy until the tiny string finally breaks.
Don't flash an immediate smile when you greet someone, as though anyone who walked into your line. Instead, look at the other person's face for a second. Pause. Soak in their persona. Then let a big, warm, responsive smile flood over your face and overflow into your eyes. It will engulf the receipient like a warm wave.
