It’s easy to push things off till later, especially reading your emails and replying to them.
But then you pile them up and 5 emails unread turn into 500, and you fall behind.
If your inbox has too many advertisements or junk filling it up, then unsubscribe, throw out the trash, so you can filter out what’s important.
Read the emails as you get them (like my daily blog posts) and reply to urgent ones as needed.
Lead a life where your emails have 0 unread. Lead a life of the 0 inbox rule.
