Great things require perseverance. Just like a game, that needs to be played consistently over a long time to reach true proficiency. You can invest more or less time, but you need to be consistent. Over time, the skill level already reached at a game is lost only very slow. This is similar to riding a bike or skiing.
It's very hard to persistently do hard things. I believe it's impossible to be persistent without love for the things we do.
