Commitment works by exclusion, and the exclusions are invisible, which is why an overfull life feels accidental rather than chosen. Each agreement closes a set of alternatives you never watch closing, so the cost turns up later as a shortage of time you cannot trace to any decision. Choosing is not a loss of options. It is what having a direction is made of.

Before the next yes, say out loud what it rules out. If the trade is worth making, agree properly and stop mourning the rest of the list.
