The document discusses a system called "Inbox Zero" for managing email overload. It recommends processing emails by quickly answering escalating questions about each email to determine the required action. The goal is to decide on an action and convert each email to a to-do rather than just checking emails. It suggests scheduling dedicated "email dashes" to focus on processing emails rather than being in a perpetual state of checking emails. Creating filters can help reduce noise from frequent but non-urgent emails.
