Growth is when you stop needing the last word and start wanting the right one.

Needing the last word is about winning the exchange rather than settling the question. It feels urgent at the time and usually costs more than whatever was being argued over, because the other person stops listening the moment it turns into a contest. Caring about the right answer is a different aim. It lets you lose an argument and still come out ahead.

In the next disagreement, stop one sentence earlier than you want to. Ask what they are actually saying before you reload. You can always add something later, and mostly you will find you did not need to.
