# Inbox Zero principle The idea of Inbox Zero is to try and keep our inboxes clean. To do so, we need to regularly review our inbox to avoid accumulating information there. We can also introduce automation in order to automatically clean the clutter. Those inboxes can be anything: e-mail inbox, work to process, fleeting notes in our Zettelkaster, etc. Inbox zero helps keep a clear view over what remains to be processed/done, instead of having a huge pile of content that is hard to make sense of (i.e., a big pile of dirt or a big ball of mud). This helps avoid feeling overwhelmed and stay on top of things. Inbox zero is generally associated with the email inbox, but it applies to all sorts of contents that need to be reviewed, processed, and organized. For instance, we can create an inbox folder for project documents, work to be done, fleeting notes in our Zettelkasten, etc. As such, this concept is also very useful for [[Personal Knowledge Management (PKM)]] Inbox zero has been heavily recommended by [[David Allen]] and included in his bestseller: [[Getting Things Done (book)]] (GTD), cfr [[Getting Things Done (GTD)]]. ## Related - [[Tips to maintain Inbox Zero]] - [[Getting Things Done (GTD)]] - [[Getting Things Done (book)]] - [[Two minute rule for productivity]] ## References - Articles - Everything you need to know about the Inbox Zero method: https://blog.superhuman.com/inbox-zero-method
