I have found "Thinking in Systems" [0] to be a good book for crystallizing "systems" concepts in abstract. For example, it includes discussions on feedback loops, bottlenecks, equilibrium, etc. IIRC, it has been used as a textbook for systems theory classes in some universities, but it's concise and written for a general audience.
