The future tense lets us speak confidently about people we have not yet become.

The future tense lets you make claims on behalf of a person who does not exist yet. You speak with real confidence about what you will do, and the speaking feels honest, because you genuinely intend it. But the one who has to carry it out will be tired in ways you cannot predict, in circumstances you did not model, holding priorities that have quietly shifted.

When you promise, promise on behalf of a plausible version of yourself rather than an ideal one. Ask what a tired version would still manage. And when you fail to do something you sincerely meant to do, treat it as a forecasting error rather than a character defect, then adjust the forecast.
