> At some point my brain hits what I think of as an “activation level” and I suddenly “flip” my attention and focus to the job at hand. It feels like what happens when you’re kindling a fire, and you get a little bit of flame in some dry stuff, and then you “pop” that flame (attention) into the larger pile of fuel.

What a wonderful way to describe such a feeling. I have struggled, and still struggle, with the same issue. I have no idea of get that switch to flip on faster, but I hate wasting so much of my day just waiting.
