We accept commitments in the moment and live with the slow creep that follows. The Decision Ledger is a compact discipline: whenever you say yes to a recurring task, a new responsibility, or an important favor, immediately record one sentence—What I agreed to | Why it’s important | One clear guardrail (when/how/who). That short note creates an external memory, clarifies expectations, and gives you a tangible artifact to review during a weekly five‑minute ledger check. This episode explains the behavioral logic (decisions decay without a recorded why), provides three calm, testable sentence templates for work, family, and community, and gives a simple nightly/weekly routine to keep the ledger live without performance. Practical, private, and reversible: stop scope creep before it starts by putting your yes on the record. If this matters to you, subscribe — and record one Decision Ledger sentence tonight.
