Everyone has differences with each other but at the same time we also have many things in common. There are probably even more noticeable differences between people from different countries, because of different languages, values and ways of dealing with people. These could sometimes lead to confusion, annoyance or even conflict.
Only when you discover yourself by reflecting and empathize others, you can change your perspectives, and have a constructive relationship with people from other cultures. In the end, synergy and more learning will be sparked. Diversity is not for nothing!
