As I travel a lot and see a lot of people, either as fellow travelers or as the people from other cities and countries. It's really interesting that how much you make communication with people, you learn a lot about them. There are lots of targets for making communication with people for everybody. Some want to make friends, some others to know about the cultures, some for trade, etc. The point is we are living in an era that we can make communication easier. For example, you don't have to travel between two cities or two countries to see a friend! It's laughable to say something like this now, but it was about 100 years ago!
Nowadays we can have communication with our friends easily via social networks. For example, I'm working with one of my friends who live in Australia on a project, although it's been for a long time that I haven't seen her. Based on Richard Branson's idea, one of the fifth key points of success is making communication with people. Having a good friendship with people all over the world could make you feel better to have a lot of circle of friends, or eventually could lead to a win-win result. I mean you can even find co-worker among them as well as I've done a lot before.
I've made a lot of friends on my trips, in the companies I've worked for, in bodybuilding clubs, in mountaineering courses, and wherever I've been so far. As I told before, today is the era of communication. Don't make your circle of friends limited and make communication with every sort of people regarding your dignity!
