The context for "open loops" here is David Allen's "Getting Things Done" or GTD. A commitment that your brain is still holding onto because you haven’t clarified what it means or what to do about it.

I also enjoy Getting Things Done Fast, which is a seminar recording. It gives a great high level overview, with many practical exercises throughout.

(Slightly hard to find these days, though.)
