Run two burners at high for a defined sprint

Pick two domains to maximize for a bounded period, and accept the other two will idle.

Why it works

Constraint narrows attentional scope, and a narrower scope produces better cognitive resource allocation. Rather than spreading finite willpower across all four, concentrating on two lets those two receive the depth of attention that meaningful progress requires. Time-boxing the sprint contains the opportunity cost.

How to do it

1. Choose two burners that most need fuel right now, given your current goals.
2. Explicitly set the other two to "low" for the sprint duration (weeks or a quarter).
3. Define what "low" means concretely — minimum viable commitments for the idling domains.
4. At sprint end, reassess whether the two-high setting should continue or rotate.

Evidence

Selective attention and cognitive load research support that focusing on fewer tasks improves quality; multitasking costs are well documented in the cognitive science literature. (mechanistic)

The two-burner sprint is an applied heuristic; the attention research involves task-switching, not life-domain allocation directly.

Common mistake

Choosing two high burners but never defining what "low" looks like for the other two, so they quietly drain energy through guilt and reactive commitments.
