I've tried a number of these activities. What I've found is that most if not all the ones I've tried require and imply screen time. I go down rabbit holes of scrolling phone for the perfect sofa, the perfect cycling jersey, the best mountain airbnb, and so on.

The only real way to escape smartphones is to live a 1970s life where the only things you know come from other people or the radio/tv. I have a slight yen to try this but I can't bear to actually try it. It would be like cutting off a limb. I'd be so information poor.
