I do not pretend to be a particularly skilled programmer, but in my not so long career I have picked up a bunch of tools: a few algorithms here and there, some data structures, some programming techniques like encapsulation, late binding, higher order functions, pipelines, various form of polymorphism (dynamic, static, ad hoc, inheritance based, structural or whatever), some concurrency patterns (message passing, shared memory, whatever). I end up using whatever seems more appropriate to me for a specific problem depending on intuition, personal preference and experience.
Now, various subsets of the items above have been labeled with different names (functional, procedural, OOO, generic, whatever), but of course most of the time no two people can agree on which subset deserves which label.
I must not be the only one, because a lot (but not all) of very successful languages are not very opinionated and let people mix and match bits as needed.
