I agree, but struggle slightly:
In the past I've cut out the news and felt much better fairly quickly. However, it gets to a point where there's something that happens that I should be aware of - like the annual budget speech, or something related to my industry that's hit a headline.
I guess I need a means of separating the 99% outrage-inducing, unactionable mainstay from the 1% of things that I genuinely need to know about.
First, I started by stopping reading daily news; stopping refreshing the headlines every time I had a few minutes; stopping getting alerts; avoiding 'news 24/7' channels like the plague.
Then I stopped reading weekly news - what was the point? Whilst it's less of a burden that daily/hourly/minutely news, it's still unactionable for me - it has no utility, as you say.
But then it's been months and things have happened that I should know about, and the only option I have is to go back to getting alerts and 'triaging' my interest in them - except that this means that I have to process each headline again, and I'm basically back where I started.
