Interesting thought about creativity- many artists seem more creative when uncomfortable as you put it chico, but I don't think it applies across the board. I think creativity requires both experience and openness - the kind many people avoid because it isn't safe (or comfortable). Well, that could open up a whole new topic other than the Red Book, but Rohche's comment got me thinking.
Sometimes life can paralyze a person where they are in so much pain creativity simply isn't of interest to them; life itself is no longer of interest.
As for Jung, I've only seen portions of The Red Book, and if I were at someone's house where it was sitting out on the table, no doubt I'd be looking through it. But I tend to find Jung nearly unreadable - though interesting. I don't think most of his books were written in "discomfort" but from a great intellectual capacity, and to a certain degree openness to the possible.
For awhile Jung was of great interest to me - now it's no longer the case. Though I'm sure the book is fascinating for those caught up in Jung's perceptions.
I think Rohche is onto something about creating our own spiritual life - but what about those who have fallen into the abyss? Are those souls irretrievable?
Sorry again, chico for the tangent, but blame Rohche, not me!
