Beloveds, it is not all that you have to do that makes you tense. It is all you haven't done. It is the accumulation of the past that tires you. The solution is so simple. Do not accumulate the past even in the sense of day-to-day things to do. Perhaps what is left undone can stay undone. Maybe it doesn't matter. In any case, do not keep carrying it over your shoulders for then you get weighed down.
