This is oddly worded and has some strange conceptions.
If you open a coffee shop and can’t handle the stress and can’t manage to afford to operate it… then you have failed. If you open a coffee shop and run it well for a few years and decide to sell your functioning business or largely step down from active management with new leadership… then you successfully ran a coffeeshop and did not fail at it.
If you marry someone and divorce them, and its anything but a mutually agreed, low to no drama, no fault divorce, then yes the relationship and marriage failed.
Now the book/author example is worded much more sensibly. If you write books for a few years, and can support yourself from this or hell even if you really enjoyed it, and then you move onto something else, I don’t think anyone would consider you a failed author. You did the thing, got some works published, excellent, you are a successful author!
A friendship that doesn’t last… in most cases, is kind of objectively less of a friendship than one that lasts for a long time. It can still have been a real friendship, but it obviously was not important enough for one or both people to continue it if they … did not continue it.
People going through hobbies as phases is linguistically literally correct, as many people do this. I do agree though that phrasing this derogatorily as if there is somehow anything wrong with changing hobbies overtime is somehow bad or indicates anything negative, unless youre doing that extremely overenthusiastically and/or fiscally or physically dangerously.
Fandoms do ebb and flow. They rise and fall in popularity and enthusiasm. I again do not really see how this is somehow indicative of a culture that prizes only permanent things.
Perhaps by now its obvious I am autistic but… it doesnt make any sense to praise or criticize a fandom by its popularity alone. Praise or criticize it by the kind of community it fosters, the in jokes, the style, the lasting marka its made on other things, the quality or appeal of its content.
I mean I agree with the ending of this, that temporary things can still have been good, but… yeah a good bit of this person’s examples seem to me to be not well thought out.
