Several weeks ago I set my phone to sleep from 6pm to 1pm the next day, so I don't get any notifications.... Only important ones, that I select get through.

It was wearing me out thinking I have to be available during every waking minute.. I don't start or stop working at those hours necessarily... But 6pm is a good time to stop I believe... and 1pm is when I start my bigger projects and work on them for five or six hours.. I don't like to get an endless stream of alerts. It gives me a proper ending time, which I think is very important.
