How to ThinkIn the Age of AI

Separate functions in shared spaces with orientation, time…

Resolve space-function overlaps through orientation changes (facing different directions), time-based zoning (function varies by time of day), physical markers (specific lamp only on during deep work), or relocation — not through willpower to mentally separate functions sharing the same physical space.

When This Fires

  • When you must use the same space for multiple competing functions (work + relaxation, deep work + meetings)
  • When working in a shared space feels harder than it should despite adequate physical conditions
  • When spatial separation is impossible (studio apartment, shared office, travel)
  • Complements Optimize your workspace for your highest-value activity… (prioritize highest-value activity) with tactics for managing the lower-value activities in the same space

Common Failure Mode

Willpower-based separation: "I'll just discipline myself to work at this desk even though I also game here." The willpower works for a few days, then the gaming association wins because it's the stronger, more rewarding association. Structural separation (turning the monitor to a different angle, using a different keyboard, or changing the lighting) would have prevented the conflict without requiring willpower.

The Protocol

(1) Identify spaces where multiple functions overlap (your desk serves work + entertainment, your dining table serves eating + work). (2) For each overlap, select the most practical structural separator: Orientation (face different directions for different functions), Time (different functions at different times, with clear transition ritual), Marker (visible physical cue that signals which function is active — a specific lamp, a desk mat, a particular chair setting), Relocation (different seat or corner for different functions). (3) Be consistent: use the separator every time. The brain needs repeated pairing of cue + function to build the association. (4) The separator should be physical and visible, not mental ("I'll just think of this as work time"). Physical cues are perceived automatically; mental intentions require willpower. (5) If multiple separators are needed (orientation + marker), combine them. The more perceptual differences between function modes, the stronger the separation.
