I speak German natively and through work I'm fluent in English. We have a lot of cooperation with French and Swiss-French people, so I tried learning French earlier this year, but failed. However, a colleague from work introduced me to the concept of conversation groups. I realised a lot of people had no problem to learn German within months (mostly Spanish who came to Germany to find work). This made me start transforming my school-learned Latin into Spanish almost with ease, I understand it, but can only produce very simple sentences. So if you happen to be able to join such conversation groups, do it, it is great for learning languages and also brings you down thinking about your own language when after two times repeating a sentence nobody understands you. You have to try hard simplifying your mother tongue, which is a real brain teaser.
