"We call an event or incident a breakdown when we are interrupted in the midst of going about fulfilling our commitment."
Exactly. Breakdowns (problems) only exist in terms of getting in the way of achieving a goal. Additionally, they always involve some sort of dilemma or conflict, forcing us to consider doing something we would prefer not doing. A deeper question is whether that dilemma is real or illusory; whether the rock is immovable and the hard place impervious, or whether they only seem so in terms of a faulty understanding of the situation.
Hal promises to continue with a discussion of "avoiding breakdowns." It'll be interesting to see where he's going to go with that topic, as I would contend the vast majority of avoidable breakdowns are encountered due to iatrogenic sources, induced by previous "good intentions;" a source similar to that that makes the aforementioned dilemmas seem real.
