I have gained a great deal of value from the stoic/Buddhist traditions around acceptance of a certain amount of suffering, but 'learn to appreciate your suffering' is just plain silly in most cases. If masochism is your thing, fair enough, but don't act like it's what everyone should do.
The author didn't even indicate you should do everything to avoid suffering, but you're going after the idea like a ghost has been haunting you with it. I would normally assume you meant 'appreciate' as one might appreciate an avalanche - from the farthest possible vantage point - but you took that right to the "any of this 'x' bullshit" level right form the hop, just because the author made a reasonable assumption. (which was not that we should "do everything to stop suffering"). Nearly every human and other living creature seems to act in accordance with the author's assumption, so it's probably not a bad thing to assume.
Suffering is bad - arguably as bad can be. If I must live with it, I'll appreciate how polished the turd is, but if I don't have to live with that turd, why would I?
