Applying labels on my emails by keywords, sender, etc. I know I can search them, but having them sorted in labels makes everything easier to find without actually searching.

I also work hard on keeping my email inbox empty unless something has to be done on a specific email.

I also try to avoid reading news at work (source of distraction), but I want to keep myself as up-to-date as possible so I made some IFTTT applets which monitors some RSS feeds combined with some keywords I'm interested in. If there is a match, I get the URL sent to my Pocket account and the article will be sent to my eReader (supported natively by Kobo), and synced to be read offline while I commute to work or go back home.
