Ask HN: How to start using mental models?

With so many people commenting on a recent thread "Mental Models I Find Repeatedly Useful"[1] that this the list, although useful for people who already know how to use mental models, but is of not much use to the ones that are unaware of how to use these models or are not familiar with the models[2]. Could you suggest some reading list/knowledge path to be trained with mental models? Or is doing MBA the only option[3]?
