Another analogy that might work is chess. I’ve only ever played “classical” chess and when my son got interested in playing I would crush him every time. Up until the point he got into bullet chess and was literally grinding out dozens of games a day where I’d casually play a game of classical chess like once or twice a month. His confidence and ability skyrocketed and I’m not even a challenge for him anymore. Now I’m not a real chess player, and there are areas of his game that are definitely weak compared to classical chess players who have played as many games as he has. But to turn around so quickly from not being able to win a game against me to dominating me in every game was impressive.
