Disclaimer: This article is written for developers with a job that does not depend on emails, social media and texting. Most of the points are based on my personal experience.
We live in an age where social media, text messaging and emails have become an integral part of our lives. The average American spends more than 40 minutes a day checking their Facebook feeds. Whereas these tools are useful for communication and productivity, they may also be a distraction on your productivity. By applying little discipline, you can easily improve your productivity.

If you're active on one or more social media apps (Facebook, Twitter, Whats app and so on) and check them frequently, it could be a distraction to your focus and productivity. How often do you check your emails? Are emails an important part of your job function? Most of us have text messages enabled on our mobile devices.
The Lifehack's article advice is to never check your email in the morning.
According to Morgenstern, checking your email the first thing when you get into the office each morning is problematic because it can a false sense of accomplishment. You answer 40 emails and you feel like you've done a lot of work, but in reality you probably still have piles of paperwork, meetings and phone calls to make. Answering email is essential to doing your work, but it isn't always something that is actively making money for you or your company.
Unless your job relies on social media, emails, or texting, you should disable automatic notifications. Allocate a block of time during the day depending your frequency and the importance of the emails. You could check your email once every hour or 2 hour block.

“Allocate a block of time to check your social media, emails and text messages.”

Once you allocate a block of time to check your social media, emails and text messages, make it a habit. Once it becomes a habit, you will never think about it.
