I would turn that on its head: Provide several motivating examples, together with concrete solutions. Once you've provided a couple of those, then you can call attention to the commonalities that unite all those solutions. At which point, the abstract explanation is almost trivial. For example: My understanding of monads ultimately came together rather quickly and painlessly. After I had initially just given up on the whole thing. And then I watched Scott Wlaschin's Railway Oriented Programming talk (https://fsharpforfunandprofit.com/rop/ https://fsharpforfunandprofit.com/rop/). And then I learned what's really going on with LINQ's query DSL and SelectMany. And had someone show me how to easily compose Optional types without having to forever be explicitly interrogating whether they have a value or not. With all that under my belt, the pattern suddenly became rather obvious. What did not help me in any way was any article that explicitly sets out to try and explain monads. They are all, as far as I'm aware, guilty of tring to sow the seeds before tilling the earth.

It was quite similar for me. Scott Wlaschin's Railway Oriented Programming and its other articles on its site (and in particular https://fsharpforfunandprofit.com/series/map-and-bind-and-apply-oh-my.html https://fsharpforfunandprofit.com/series/map-and-bind-and-ap...) helped me greatly too. I liked its idea of an "elevated world". Another helpful source was/is https://wiki.haskell.org/All_About_Monads https://wiki.haskell.org/All_About_Monads. But I thought a lot about them for the past few years. I tried also to make a detour through category theory but it did not help except for getting a lot of books in my library. Another helpful article was Philip Wadler's "Monads for Functional Programming" (http://homepages.inf.ed.ac.uk/wadler/papers/marktoberdorf/baastad.pdf http://homepages.inf.ed.ac.uk/wadler/papers/marktoberdorf/ba...).
