About 4 months into my channel, I made a video "Americans are Strange" (from the perspective of a seasoned expat). I recorded it in Czech, and looking back, my Czech was so awful! The video went viral and is still my most viewed, I think it might have 600K views right now. I was getting 1,000 new subscribers a day for a few weeks after that and it got my channel monetized. I've got about 62,000 subscribers now, though I've mostly stopped focusing on subscribers, views, etc. YouTube metrics are a hedonic treadmill that will kill your creativity.
