Look at every email in your inbox, and train yourself to quickly decide what to do with it:
- Do – If it’s actionable, do the task. This could be simply replying.
- Delegate – Forward it on.
- Defer – Decide to do it later (snooze it until a concrete time).
- Delete – If it could be deleted, do it. Always be reducing your inbox.
- File – If necessary, tag it and set a reminder for later to process items in that tag.
