There's a very simple trick (originally posted by danarm) for dealing with the most harmful consequence of attention hijacks, namely, the difficulty to return to where your mind was before the hijack occurred:

'Most harmful consequence' is highly situational here and evidently varies a lot from person to person. When I am returning to the task I have no particular need for a piece of paper to redirect me. The task is right there on the call stack, I'm just not doing it. Perhaps my hijackers are of a different kind.
