I've been thinking about this idea lately in the context of a gratitude practice, which under that name has never sat well with me for reasons having to do with my ex-Catholic upbringing. https://twitter.com/visakanv/status/1326918310919856133
But I look back on my life so far, and in every period there were things I liked that were unique to that time. And some of them I really made the most of, and I feel good about it, and others I didn't, and those are the things I most often find myself trying to recapture.
So for me, gratitude is not a particularly helpful lens, but it is really useful to think about appreciating the good bits of the now, because all things eventually pass, and I can only enjoy them while they're here rather than figuring I'll get to it after the bullshit is over.
