This is one piece of advice that sound true and insightful, but in my opinion doesn't really hold up to scrutiny. An example of what I mean is the saying "perfect is the enemy of good", which directly conflicts with the above. Since I'm from the north, outdoor gear is a good example of this — there is no hardshell jacket in the world that ticks every box in my checklist. I've been through the lineup of both known and…
I don't think you're contradicting the advice. The advice was basically to find one good enough, then search a bit more. You found something good enough, then spent a unbounded search time on more alternatives. This is precisely what the advice told you not to do. You did it and are not entirely satisfied with the outcome. This doesn't seem to contradict the advice.
"Then, don't stop, keep searching until you find a better one."
and turned it into:
"then search a bit more."
There was no mention of "unbounded search time" in the original maxim, and the person that you're responding to is following the maxim exactly ("don't stop until you find a better one").
Don't get me wrong - I think your interpretation is reasonable and a better idea than the original. But everyone takes these maxims and adds layers of interpretation and good sense to such a degree that you may as well have just trusted in your good sense to begin with.
If the original maxim had been more actionable ("then spend no more than 20% of the time you originally spend searching to attempt to find a better one, stopping if you do so") it might be more helpful, but it loses that air of folksy wisdom that these maxims love to put on.
