Before committing, imagine it is three weeks later and the plan flopped. List five plausible reasons: cost creep, calendar clashes, supplier delays, or optimism about energy. Now adapt: trim scope, add calendar buffers, set a clear exit rule. By rehearsing failure compassionately, you prevent it, while honoring emotional realities that spreadsheets often overlook.
Start with how this usually goes for people like you in contexts like this, then cautiously adjust. Whether estimating delivery times, budgeting side projects, or predicting adoption, base rates anchor expectations. Without them, vivid stories dominate. A modest, sourced baseline calms imagination, reduces anchor drift, and grounds ambition without dimming it.
