Commit to a single task for the full session

Flow is incompatible with multitasking — choose one thing and protect it for the block.

Why it works

Multitasking distributes the attentional resources that flow requires to be concentrated. The brain cannot sustain two goal-directed sequences simultaneously; what looks like multitasking is rapid task-switching, each switch costing attention and restarting the accumulation of absorption. Flow demands a single channel of goal-directed attention.

How to do it

1. Write the single task on a sticky note and place it where you can see it.
2. If a competing thought or task arises, write it on a "parking lot" list without acting on it.
3. Commit to returning to the main task within 5 seconds of any self-interruption.
4. Schedule a review of the parking-lot list at the end of the block, not during it.

Evidence

Multitasking research consistently shows performance deficits and increased error rates; heavy media multitaskers show reduced ability to filter irrelevant information, which is structurally incompatible with flow absorption. (observational)

The evidence is on multitasking costs, not on flow directly; the link to flow is mechanistic rather than experimentally isolated.

Common mistake

Using the parking-lot list as a reason to constantly switch tasks ("I’ll just quickly deal with this since I wrote it down"), defeating its purpose.
