Are you buried by an inbox filled with emails you haven't read? Tony Hsieh, CEO of Zappos, came up with a unique way to tackle his emails without zapping his precious time! Yesterbox is the technique of dealing with yesterday's emails today. As Hsieh explains, "The great thing about this is when you get up in the morning, you know exactly how many emails you have to get through, there's a sense of progress as you process each email from yesterday and remove it from your inbox, and there's actually a point when you have zero emails left to process from yesterday."
