2 months ago I've started playing TFT, today I hit Master

So about 2 months ago I've started playing TFT. Set 13 is my first set ever (well actually I played a single set 5 match) and today, after 230 games, I hit Master. It feels great because TFT is the first competitive game I've ever gotten into, and I enjoy this game so much. I don't know if it's common, but it feels insane to hit such a rank when 2 months ago I had almost no knowledge about the game. I've learned a lot about the game, and I will of course learn more and hopefully hit higher ranks.
