Frequently asked questions

What is a nightly inventory in AA?

A nightly inventory is a daily self-reflection practice rooted in Step 10 of Alcoholics Anonymous: "Continued to take personal inventory and when we were wrong promptly admitted it." It involves reviewing your day to identify where you acted with fear, selfishness, dishonesty, or resentment — and where you acted with integrity.

How do you do a Step 10 nightly inventory?

Sit quietly at the end of the day and ask yourself: Was I resentful, selfish, dishonest, or afraid today? Did I cause harm to anyone? Do I owe an apology or amends? What did I do well? Many people write their answers in a journal or use a guided check-in app to build the habit.

How long should a nightly inventory take?

A nightly inventory typically takes 5 to 15 minutes. It is not meant to be an exhaustive therapy session — just a brief, honest review of the day. Consistency matters more than length; a short daily inventory is far more valuable than an occasional long one.

Is a nightly inventory only for people in AA?

No. While the nightly inventory comes from Step 10 of AA, the practice of daily self-reflection is recommended by therapists, mindfulness coaches, and recovery programs outside AA. Anyone in recovery can benefit from reviewing their day and checking in with their emotional state before sleep.
