But in an of itself doesn't create anything. Mindless content consumption doesn't even leave memories sometimes, what to say of ideas.
Before you claim it is impossible because of your work, is it really? Did you try and think of a way that was possible?
I've done many of these and they were great, including giving up the internet and computers/phones, with the exception of work. This was back when I went into the office and I limited myself to only work related tasks there. Wifi and computers were turned off and phones put away at home for a month.
It's actually somewhat difficult to break the habit and very boring. But after about the third week you start to get used to it. By the end of the month when I could go back to "normal" I realized there was very little I actually wanted back. Mostly it was a few games I wanted to play and texting with friends on a regular basis. I lost all interest in social media after it (and that's still true) and I became very annoyed by the "ding" of the phone so I turned off all notifications and set it on DND full time (and that is also still true).
Another thing that's I got out of it is I notice how much time everyone else is distracted by their phones. It's really crazy to see when you're not one of them.
