Set recurring alarms every day (for waking up and for recurring meetings)
Pick a time you want to wake up every day and stick to it. Set a recurring alarm for that time (you can exclude weekends if you want).
Now, do the same thing for any recurring meeting you have. Why? You'll focus on work and let your alarm remind you it's time to go to the next meeting. Consider setting the alarm five minutes earlier than the meeting so you have time to prep and walk to the meeting.
Set a recurring "Do Not Disturb" mode on your phone
Don't let the dozens of apps and services on your phone be in control of your life by constantly distracting you.
"Do Not Disturb Mode" works on both iOS and Android. Open your settings and turn on "Do Not Disturb Mode" from 9 p.m. to 8 a.m. While this is turned on, your phone won't vibrate, ring or cause any other types of distraction.
Once you try this out, consider widening the do not disturb window even more broadly. If you want to be really intense about it, leave your phone in do not disturb mode 100 percent of the time.
Turn off (almost) all notifications on your phone and computer
Most notifications you receive on your phone are not worth a millisecond of your time. Right now, open your phone and computer notification settings, and turn those darn things off.
Most importantly, turn off all notifications for email, including any badge icons. Email is the ultimate productivity killer. Open email once in the morning and, at most, a few times throughout the day. The few notifications you may want to keep are SMS messages and other messaging apps.
This doesn't stop with a one-time purge either. Any time a new app asks for notification permissions, deny it. You can always turn it on later.
Sign up for Unroll.me
This is one of my favorites tips on this list. Unroll.me is an email lifesaver. It will drastically declutter your inbox within 24 hours of setting up. This is accomplished by consolidating all your email newsletters into one single email.
Unroll.me will also help you unsubscribe from all those unwanted email lists you've accumulated over the years. Make sure to set it up with all your accounts (personal and business). This is the first step in reaching inbox zero. Unroll.me has helped me unsubscribe from 237 newsletters on my personal email account alone!
