How does that work with things that aren't procrastination, like doing the dishes or folding laundry? Because I want to stop the whole time (though I've developed hacks to help me get them done, regardless), but training myself to stop doing things I want to be doing seems like it would make it easier for my brain to stop doing things I don't want to do!
I guess it's like training an exit routine that I can quickly enact in those fleeting moments of self-awareness while scrolling, it's still intentional but it has to be quick and decisive or you'll just go back to procrastinating. I wouldn't ever do it while being productive because if I became self-aware of being productive, I'd just think "Nice one!"
If you'll indulge me for a tangent, if you have heard of lucid dreaming you may have heard of strategies people use to help them recognize a lucid dream. You essentially train habits, like checking your watch or reading things twice, that will help you notice inconsistencies in the dream that wouldn't exist in real life. This will clue you in to the fact that it's a dream.
Deep procrastination is kind of like being in a dream, you're zoned out and you just ebb through it mindlessly. You can train yourself some cues, mental escape hatches, that jog you into self-awareness long enough to enact your escape routine (turn off the device, get up off the chair etc)
