I've subscribed to physical periodicals in a similar effort, but they often end up unread by the end of the week. The problem for me, clearly, is the needed behavioral modification, and not the incentive to prioritize the material that I pay money for. This just adds guilt for wasting money and backsliding (I know, a bit melodramatic). So often I still idly scroll reddit or something, and hate myself once I realize what I'm doing.
Anyway, interesting list. Thanks for the reminder to make this effort again.
