The Phenomenon
There's a specific type of focus failure that doesn't get talked about enough: you sit down, you open your work, you're not even resisting it - and within two minutes your mind is somewhere else. Not on your phone. Not on social media. Just... gone. Staring at a wall, examining your hands, replaying a conversation from three days ago.
The strange part is that you watch it happen. You're aware, in real-time, that you've drifted. You tell yourself to come back. And it doesn't work.
This isn't procrastination in the traditional sense. You're not avoiding the task because it's unpleasant. You're losing the task because your brain isn't getting enough engagement signal to stay locked on.
Research on temporal motivation theory (Steel, 2007) shows that sustained attention is a function of how immediate and concrete the feedback loop is. When a task is large, abstract, or undefined - even if you enjoy it - the brain treats it as low-signal. It disengages not because it doesn't care, but because it doesn't have enough micro-level structure to stay active.

This is different from ADHD. It's a structural problem, not a neurological one. The task itself isn't giving your brain enough to hold onto.
