What does it mean that optimization logs?

Record what you changed, why, and what happened — optimization without documentation is gambling.

Example: You spend a week tuning your morning routine: wake time, exercise order, caffeine timing, task sequencing. By Friday you feel better — but you changed four variables simultaneously and wrote nothing down. Which change helped? You don't know. Next month, when the routine decays, you can't reconstruct what worked. A colleague who logged each change with a one-line rationale and a one-line result can reconstruct, remix, and share their entire optimization history in minutes.

Try this: Pick one system you're currently optimizing — a workflow, a habit, a communication pattern. Create a simple log with four columns: Date, Change Made, Rationale, and Observed Result. For the next seven days, log every deliberate change. At the end of the week, review the log and answer: Which changes had the largest effect? Which rationales were wrong? What would you try next based on this record?
