This resonates with me quite a lot. I played World of Warcraft very obsessively in high school and got extremely good at the game. I remember a quote from a Nat Geo documentary on professional StarCraft players from South Korea: "I'm number 1 in one field because I'm trying my best, and I know if I put all of my effort into another field, I will also excel. So I'm not depressed or frustrated, I would rather be confident". For me, my prior experience has given me a deep-seated confidence that I can become great at anything I put my mind to (barring any genetic prerequisites)!
