I log out of every social media website/app because the act of logging in is just enough friction for me to be mindful: do I really want to do this?

The sense of slowness creates the conditions for pausing and being mindful of what you're doing.

In spirit, this reminds me of the return to slow/analog: https://news.ycombinator.com/item?id=48084980

Consider it the no- or low-alcohol alternative to full speed. https://www.paulgraham.com/addiction.html

At work I curbed most of my internet wandering by turning off all the autocomplete and history of the browser. When I close the browser, everything is wiped. This way I have to explicitly type in the site url instead of an autocomplete in the url bar or history suggestion. I don't do anything personal on a work computer anyway so I don't need to log into anything.

On my phones it's even easier: no apps save for absolutely necessary. If I need an app while traveling or whatever, I install it only for the necessary duration then uninstall it when done.
