A personal productivity heuristic, described by the SpotMinders/Jungle Powders operator as learned from industry experience: only spend time on activities that demonstrably 'bring value.' Used to filter daily tasks — deprioritizing or cutting activities that can consume unlimited time (endless optimization, meetings, minor tweaks) without a clear payoff, in favor of the few actions with outsized impact. Conceptually adjacent to RICE Prioritization Framework (Reach, Impact, Confidence, Effort) and Quarterly Effort-Impact Scorecard (Business Lever Prioritization) but framed as a personal, day-to-day filter rather than a formal scoring system.
