What 2 years of German taught me about myself

I share the real benefits I found from learning German and English, not the obvious ones (working abroad, better conversations), but the ones I didn't see coming : words that carry entire concepts your own language doesn't have, a study method that became transferable to any big project,and a daily discipline that killed my procrastination for good. I also get into why I think 70-80% of learning a language comes down to vocabulary, a bit of a controversial take, and how the process itself became a quiet source of happiness, day by day.
