The first of these systems is actionable: When it doesn't work, it can generally be made to work. The whole journey may be an awful affair for the entire duration, but a person can usually (not always!) get there.
The other two systems are inactionable: When it doesn't work, there is no fixing it. There is no pathway, nor any journey. One can only accept that it is broken, that they are powerless to change it, and that this is the end of the road for that problem.

There are probably healthier ways to learn acceptance than this.
