I always have my phone set to Do Not Disturb unless I’m expecting an important phone call.
Because the distraction of bells and notifications is enough to ruin anyone’s concentration. It isn’t worth it.
What are you expecting might happen if you miss a notification or a text message?
To test this out, try leaving your phone at home once per week (bring a book or an unconnected player mp3on the train or in your car instead).
You don’t need to see almost anything that comes up on there.
With my phone always set to not disturb me, I’ve been much more able to concentrate on my work without fracturing my attention.
Because that’s what notifications do: they fracture your attention. The habit formed by fracturing your attention is an unfocused mind.
Put your phone on Do Not Disturb mode by default. You’ll thank me later.
