Today Business Insider published GS Elevator's Guide to Being a Man. I anticipated a douchey rant on bottle popping and black cards (sorry finance friends) but was pleasantly surprised by the list of very on-point lessons for the modern man. So gents, listen up. Read this. Do these things. Consider it like a post-snapchat era update to dad's Brooks Brothers Guide to Being a Gentleman. And get off your phone. No self respecting man takes a selfie.
