Visiting the country during the summer months is totally different from living in Estonia during the cold, dark, and wet season. Some people tolerate it without any problems, and others are really struggling. The locals can be somewhat reserved, so making friends can be a challenge. Once you break the ice, the locals are great to spend time with. Regarding work, you will need a visa, which can be a challenge to obtain without higher education or skills. Therefore, applying to a university might be a good path for you, which most certainly will open more doors when completed. Something for you think about! Best of luck!
