I find that 'excess mental activity' blocks peak-performance when coding. Excess mental activity can be described as 'aversions/judgements/fears' about the work to be done - self-talk like "this looks hard", "fuck I hate this build system", etc.

I try to just stare at the code without judgment for a few moments, then let the fingers do their thing. Sort of a meditative practice - quiet mind instead of quiet eye.

YMMV! :-)

My version is a bit different: It really helps to know my editor well enough that I just look at a spot on the screen and the cursor goes there (without conscious thought).

That's probably not quite the same thing as the article is talking about, though...
