Stop relying on fuzzy memory. Capture your prediction, reasons, and uncertainty before acting, then revisit after outcomes are known. Over time, the archive turns guesswork into calibrated foresight, revealing when you’re reliably right, where you overfit, and what deserves slower thinking.
Forget lab jargon. Pair two plausible options, change one variable that matters, and live with each long enough to feel results. Your kitchen, commute, calendar, and energy become the testing ground, making improvements obvious without spreadsheets, perfectionism, or sterile distance from real life.
Write your bet before acting and keep the receipt afterward. When outcomes disagree with confidence, you adjust, not agonize. The growing stack of comparisons and notes reduces second‑guessing, strengthens future choices, and converts regret into refined playbooks for similar moments.
