Unfortunate fact
A classification that keeps on being helpful to me: Can I, personally, do something about this? Or is it outside my control?
The former is a problem, the latter an unfortunate fact. With extra resources, access to different systems, or more knowledge and unfortunate fact could become a problem: And that requires those sets of problems to be solved first.
There is a certain kind of zen in the realisation that some things are just what they are.
