Understanding why you do something can become another excuse to keep doing it.

Understanding the origin of a behavior gives it a kind of legitimacy, and that legitimacy quietly becomes permission. This is how I learned to cope, this is where it comes from, this is why I am like this. Every part of that can be true and none of it obliges anyone else to keep absorbing the consequences.

When you notice yourself explaining a pattern, finish the sentence differently. Add what you are going to do about it, specifically, this month. Explanation and responsibility can sit in the same paragraph, and when only the first one shows up, it is usually doing a job.
