@sullybiker Maybe you should leave it alone for the time being and do something else.
I have found that such days are often signs that I'm doing something wrong or making wrong decisions. And if I insist on doing it anyway, there are usually consequences. And then looking back there's only: "Why couldn't I take a hint?"
@SeventhMagpie You are correct, of course. My frustration just led to more mistakes. But when you make a special effort to do something there's something of a sunk cost and you don't want to have to do it all again...
@SeventhMagpie Yes, in competitive situations the tendency to fixate on difficult routines is very common.
