I try every productivity system but analyze: is system-hopping the problem? Map productivity systems tried and duration of each. Calculate: if system-switching wastes time and prevents mastery, what's the cost? Show me the system trap: constantly optimizing system instead of doing work. Give me the system commitment: pick one, stick with it, stop switching. Include: whether I'm addicted to productivity porn, if any system would work if I stuck with it, and whether system optimization is procrastination.
