One way of seeing is that OO design and programming is an outgrowth of structured design and programming. So if you've never done it, try and design a large system using only structured techniques. Another way of seeing is that while OO design solves some problems, it introduces a whole bunch of new ones, e.g.: Subtyping, Subclassing, and Trouble with OOP http://okmij.org/ftp/Computation/Subtyping/ http://okmij.org/ftp/Computation/Subtyping/ http://harmful.cat-v.org/software/OO_programming/ http://harmful.cat-v.org/software/OO_programming/ So yeah, you might turn out to be a Lisper (or an MLer or Haskeller) and you just don't know it yet.
