Overview
The way you interact with strangers could impact your day in a very big way -- if you choose to ignore everyone you don't know, then your day will be uneventful and typical. But if you engage with other people as often as possible, you will find a huge shift in your energy and creativity. You don't have to make any new friends, but why not smile a bit more? Make silly small talk with someone as you ride the elevator together. Interaction is invigorating.
