There is a core principle in system thinking of feedback communicating with action (cybernetics, to be exact). We act and wait (consciously or not) for feedback to correct our strategy, tactics, or goals. I take a more expansive system view (complexity, where cause and effect are looser) and work with the idea of changing feedback mechanisms as a form of managing self-actualization and negotiating with life. In other words, we look for other feedback we are doing OK in our 20s, 40s, or 60s.
We can look at how well we are doing financially (I imagine most people do, although maybe reluctantly), career satisfaction, family, friends, or other forms of actualization.
