I've come to realize this. I've always been a reader, but after college and after getting into audio-books, I took to it in earnest. I peaked at reading 75 books in 2012 (and BIG ones too, History of Third Reich, Thinking: Fast and Slow, Ulysses, Godel-Escher-Bach etc...).

And after that I was like 'wew. Okay, I enjoyed that and learned a lot and have, but my life isn't THAT much better because of it.' I've definitely traded investing in relationships or other hobbies for it.

So I've since to slowed down to about 27 a year, and have found that's a good pace for me.
