I posted this in a Mastermind I'm part of sometime ago. I guess it's useful here too. --
Let's say a friend comes to you and say: "Dude, there's this new restaurant in town, pretty sweet, you should check it out." Ok, cut. Flash forward. You visit the restaurant and it's the most awesome-cool-amazing thing that you are aware of in the past century. Nice, huh?
Another friend comes to you and say: "Hey, just found the most coolawesome theater that I've ever seen! It's comfortable, full of nice people, etc etc. Man, you must check it out, like, today. Are you going today? No? Go tomorrow. Please, you need to see that". Cut, flash forward. You visit the theather and it's just a slightly cool theather.
Hmm... there's a problem here.
I don't have a well-defined theory to explain why this happens, but I got some ideas. In general, people try so hard to turn everything into an awesome thing, like, they can't living in a regular world, that it's too damn common the use of hyperbolis. And that's bad, because it messes up the communication: the listener will never take you serious.
Another way this comes up is in the internet. Your friend posts something slightly funny, you like it and comment "hahaha". Another friend posts something still funnier and you like and comment :"hahahahahahhah". And so on. In the end, to express that you're laughing hard at something, you're gonna need a hell of a string of haha's.
But, the problem is not just in talking and writing: body language counts too. If you usually moves too much, never stops your arms and legs, your movements will be automatically less meaningful for people around you. The same thing for facial expressions.
How to correct this
I noticed all this while reading hpmor. All characters expressions are meaningful: maybe because some of them received training in how to manipulate people? That's why I'm interested in mirroring Draco's modus operandi (if you haven't read hpmor yet, make yourself a favor).
- Talk less, more slowly and, when you can (and it isn't awkard), make some pauses  in your speech (btw, this helps with your second language, in case you're using one)
- Move your body less; try to communicate single points (like yeah, nay, etc) with your face. If possible, search for facial expressions images and practice in front of a mirror.
- Recalibrate the scale of your adjectives. Not everything is awesome or horrible: on one hand, it can be fine, sweet, cool, interesting, good, really cool etc, and in the other hand: not good, bad, unpleasureble etc. 
 Quoting directly from "Language Hacking Guide"
"For example, if I need a moment to recall the way to say a key word, I could say "I'm going to the..." [raise index finger analytically, take a step back, breath in deeply as if you are about to reveal the secret of life the universe and everything, and look out the window at the quest that awaits you] "... supermarket! Do you need anything?"
Don't overdo it, though.
 As native english speakers (I suppose). you can come up with better examples here than I.
This is first time actually contacting you, or anybody through blog for that matter. But you make it almost too easy(you must be bombarded with e-mail, good luck!).
I'm interested to know your strategy or preference on maximizing meaningful conversations abroad or even back home. I mean do you have any particular tactic or is it mostly random. Any public places or events that stir up conversations with strangers, any small talk lines or questions(etc. Where do you see yourself in 5 years?) that lead to insight and good conversation.
I'm from Finland and I'm going to travel a bit in asia(Okinawa, Seoul, Katmandu, Bhutan) and I find conversations as the best way to learn and experience different cultures. It would be such a waste to do it randomly if it there's is a way to do it most efficient way.
If you have any book recommendations, please make them available in amazon.co.uk with your affiliate id I would be happy to support you somehow.
Being a black traveler means that most times, people are staring at you. Some people might hate that, and on occasion, so do I. However, there are times where it has allowed me to capture some amazing photographs. My name is Afiya and I’m a professional people watcher.
Every time I return home from a trip, the first thing I do after taking a hot shower is upload the photos from my camera to my laptop. I usually return with over 1,000 pictures and at least two hours of video but I started noticing an interesting trend: the subject of most of my pictures were people. Whenever I’m planning my itinerary, I always aim to discover all aspects of what makes the country I’m visiting unique; food, eco-tourism, architecture, fashion etc. But I always add a park or a nice street cafe to the list so that I can take time out to de-stress from the hustle and bustle and of course people watch.
People watching isn’t about being nosey. It’s simply allowing yourself to be engulfed in the energy of the people and capturing it if you can. It is observing the group of Buddhist monks in Thailand chatting as they cross the street, or watching a young Thai boy sit between his parents on a motorbike whizzing through traffic. It can even be watching a group of mature Indian women sit and chat with each other or a young Japanese couple indulge in each other in a photo booth in Tokyo. But the most interesting thing to notice is how they notice you. I sometimes snap without even looking at my camera or in the direction it’s facing. Since I’m working with a point and shoot camera, I’m very unassuming. It’s always interesting to see the pictures that I’ve taken because I’m always surprised to notice that most times my subject is looking at me. Smiles, expressions of confusion, curiosity and disgust, are usually the expressions that I see in the photos that I’ve taken.
People are beautiful creatures. We express ourselves freely without even knowing. Our body language and facial expressions can express a plethora of emotions. Our culture shines through us in how we greet others, celebrate, mourn and go about our daily activities. On your next trip, take some time to sit down and people watch. Take in the noise, the emotion, and facial expressions. You’ll be amazed at how much you can learn about a location by means of its people in just a few minutes.
