Simple question. I feel I am a product of the knowledge I absorb. I enjoy Machiavelli, but I doubt reading The Prince will give me better game. I may not enjoy 50 Shades of Grey, but it teaches quite a bit of useful information.

So bottom line is hopefully you guys have a list of recommended reading. And I don't mean pick-up artists self-promotion 101. I prefer something classic, something I can brag about, something that adds value and depth and culture.

I still enjoy Machiavelli, but it's time I expand my horizons.
