How to Get Extensive Word Exposure

You're going to learn a lot more words through reading than any other input. When I watch a movie, that can be a very enjoyable form of exposure but all else being equal, I'm getting half the word exposure as reading. And then you want to also add to that good audio content, podcasts, movies, etc. so that you can develop your ear for the different accents. The standard Mexican accent is very easy to get used to vastly easier than the Dominican accent or the Cuban accent, etc. Social comments would be if you also want something else.
