Ten coins weigh more in your pocket than one bill worth more. Carrying lots of small worries is heavier than you think.

Weight and importance are not the same measure. A pile of small nagging things can drag on you more than one genuinely serious problem, because each piece is too minor to deal with and so none of them ever get dealt with. The load does not come from any single item. It comes from the number of them and the fact that you are still holding them all.

Empty your pockets this week. Write down every small thing you are carrying, then clear three in one sitting: the email, the form, the apology, the library book. You will be surprised what that frees up.
