After writing a story-like object, in which my background research indicated that it's within the realm of reasonable possibility for the first em to be created as early as 2030, with all sorts of socioeconomic disruption ensuing therefrom...

... I've noticed myself explicitly asking myself, "What would the me of 15 years from now think about that?", or "What would the me of 15 years from now want me to have been doing now?". And in addition to consider the perspective of someone facing a widescale socioeconomic disruption, I'm also using, as a comparison, what I in the present think about my younger self of 2000 AD, and trying to think of what my 2000-AD-self would have thought about by 1985-AD-self.

It's such a simple little thing, and so obvious, that it seems likely that a lot of other people have been using it for quite some time, and I'm rather a ninny for only starting to apply it at this late date. However, it has been enough to help me nudge my behaviour in certain ways that my existing tricks haven't quite managed - avoiding a bit of junk food here, reconsidering how to publicly present myself there, and so on. And so, this comment, just in case someone else has been missing out on applying this bit of perspective as I'd been.
