The emphasis on inventory is heavy only because a great many of us have never really acquired the habit of accurate self-appraisal. Once this healthy practice has been groomed, it will be so interesting and profitable that the time it takes won't be missed. For these minutes and sometimes hours spent in self-examination are bound to make all the other hours of our day better and happier. And at length our inventories become a regular part of everyday living, rather than unusual or set apart.

The Tenth Step can be a pressure relief valve. We work this step while the day's ups and downs are still fresh in our minds. We list what we have done and try not to rationalize our actions. This may be done in writing at the end of the day. The first thing we do is stop! Then we take the time to allow ourselves the privilege of thinking. We examine our actions, our reactions, and our motives. We often find that we've been "doing" better than we've been "feeling". This allows us to find out where we have gone wrong and admit fault before things get any worse. We need to avoid rationalizing. We promptly admit our faults, not explain them.

We work this step continuously. This is a prevention, and the more we do it, the less we will need the corrective part of this step. This is really a great tool. It gives us a way of avoiding grief before we bring it on ourselves. We monitor our feelings, our emotions, our fantasies, and our actions. By constantly looking at these things we may be able to avoid repeating the actions that make us feel bad.
