I really like practicing stuff, really really like practicing stuff. All the talk around here about 1-frame links just makes me drool. But now I'm running into a problem: Doing something really hard always feels like an achievement, and the harder the thing is, the more of an achievement it feels like when you do it. But practice can scale the difficulty of tasks too much sometimes. I find that I often end up over-grinding so that something stops being hard, and at that point it doesn't give nearly as much of a rush when I do it. This is especially bad when I'm constantly failing at a task, and then go from "can't do it at all" to "don't have to try" without that thrilling bit in between. The usual thing when that happens is to raise the bar, but you still leave open the possibility of over-grinding again. You can reach a point where it isn't feasible to raise the bar, either because there isn't any higher to go or because the improvements become too subtle to form concrete goals. There are some tasks that seem more resistant to over-grinding, but I'm not really certain about what they are (I have a kinda crappy memory) and I don't know if there is some way to categorize them so that I would know "oh this is a X task, so I won't over-grind it." So what kinds of things remain demanding after intensive practice? Is there a pattern?
