If you keep your phone on your desk while working, you get distracted.
If you turn it down, set it to silent or vibrate, you still get distracted.
If you put it somewhere else in the same room, you still get distracted.
If you leave it in your bag or in your coat, you still get distracted.
If someone separates you from your phone, you still get distracted.
And this means that you have increasing difficulties both when trying to access knowledge that you already have and when facing new problems that require new information (see Ward et al., 2017).
The most reliable way to avoid this is to train in being intentionally distant from your phone. It might sound as a difficult thing to do, and still nurturing a habit of doing without distraction can give a concrete and tremendous competitive advantage. Professionally, personally, and even sentimentally.
Today is a great day to start.
