Hi there. I've been playing the game for a year now (started October 2016), and I've gotten to Diamond three seasons in a row. I've accomplished quite a bit, but I still know there's a lot of room for improvement. When I first started, I felt like every game was a new world to discover. I was enjoying every second, every play, every new card or synergy that I encountered on the ladder. But as time passed, and I learned more and more about the game... that "learning mindset" disappeared. Instead, now I feel disappointed when I lose (and I lose a lot more than when I started as a rank 30), because I feel like I should be applying all the knowledge I aquired in the months I spent playing. And maybe I'm doing it? But it still feels like I could do more. And I still absolutely adore this game and I want to play it for as long as I can, so I'd like to enjoy winning and losing like I did before.

My question is: is it possible to regain that "learning mindset" that was replaced with this "winning mindset"? And if it is, how do I do that?
