I was in Hamburg - Germany at 08.2019 for 1 month. It was so good experience for me. Because i met some people and made conversations. It was about what is happening in Germany, their tradition, habits and how all systems work. So i want to share with you my experience. 

      Their money is Euro as that you know and this is too much important thing in the world. Because you earned money is meaning. So you can eat, drink, wear, live whatever you want. If you don't have a diploma about your job, don't worry, can help to a who needs help and earn money 10-15 € for an hour. 

      Their systems works disciplined because they care your life. So you can do whatever you want with your earned money without dont hurt somebody or dont risk their life.

      German people can look they are not friendly because of their life vision. Actually everyone is interested in their own life so making few friends as it's supposed to be. And then look not friendly. I think this is the right way :)
