But I will make the obvious point that does not seem very fashionable these days. What if we chose instead to cultivate self-discipline? This project is a technical fix to a human problem, but human problems can also be addressed with human solutions. Is there no value in doing things the time-honored way?
Personally, I'm not addicted to social media but I do have a sweet tooth. The classic hack here is not to have sugary things in the home, or only in such small quantities as to neutralize the problem. But these technical fixes are expensive. Restaurant desserts are poor value compared to an industrial-sized pot of Nutella, consumed slowly.
Well, I've discovered that, with practice and determination, and of course some rules about quantities and time windows, it is in fact possible to resist temptation, even when it's sitting right in front of me all day. Personally, I find this human solution to be liberating and empowering.
