I don't use Ruby, and don't do OOP either, but my favourite talk is still Sandi Metz's "All The Little Things" and I think that's where she says "prefer duplication over the wrong abstraction." That's really changed me. I've since been seeing DRY and other misapplied dogma in a new light and have grown much over the years since.
Great quote. Link to the talk? When you say you don't use OOP, are you saying you use functional languages or you use imperative languages but don't do any of the OOP design crap?
