Marco Arment writes a beautiful example of why some behaviour we all see (I at least) every day is absolutely futile: trying to change others’ behaviour out of a sense of ‘rightness’. I’m guilty of it too of course. Telling other what to do and how to do it. It’s not wrong, as Marco writes, it’s probably just not going to work. It’s better to use the ‘unwanted’ behaviour, or plan around it. Make it so that the behaviour apparently inherent in your family, colleagues or humans in general results in what you want, without changing that behaviour itself, perhaps not even directly addressing it.
