When estimating time, money, or effort, anchor on data from the last five comparable cases, not hopes. Ask, What usually happens? Then adjust for specifics. This protects against optimism and planning fallacies that charm you into overpromising and quietly underdelivering under pressure.

Imagine your quick decision has failed. Name the likeliest reasons in two minutes. Now add one step that blocks each cause—a calendar alarm, a second opinion, or a clearer exit rule. Pre-committing to safeguards makes failure less surprising and far less costly.

Before acting, write a brief forecast: what you expect, confidence level, and deadline. Later, compare outcomes to predictions. This humble ritual exposes biases, improves calibration, and grows trust in your own signal, because accuracy replaces bravado as the measure of good judgment.
