For many years, my reading of Step 10 was:

Continued to take personal inventory when we remembered to do so, and when we were wrong (which seemed to happen less and less frequently) often admitted it eventually

In addition, I was convinced that the Big Book talked about taking inventory in the morning and the evening (it doesn't -- that's in Step 11, and it's not actually talking about inventory). So I would do inventory in the morning as well -- sometimes.

The section in the Big Book on Step 10 seems to advocate something quite different. It appears to be suggesting that the "taking of inventory" should be more or less continuous, and that the period between doing something that is "wrong" and admitting it should be shorter and shorter. In fact, Step 10 comes very close to advocating awareness meditation, where I am aware of each thing I do as I am doing it.

Awareness meditation is something I do not find easy, and I am a little envious of my 12-Step friends who seem to do it so readily. But I definitely find that it is easier to keep up the momentum of Steps 4 thru 9 if I practice Step 10 as the Big Book suggests.
