For those who don’t get the reference, Amazon’s founder and soon to be former CEO, Jeff Bezos (the richest dude in the world, even after a divorce) often sites his most held belief that he and his employees should always act like every day is Day 1. It’s a startup mentality. No matter how big you get, if you come into each day as if it’s Day 1, that a great way to focus your efforts.
I’m actually a huge fan of the concept. Bezos even has “Day 1” as the name of the main corporate headquarters building
