I've been pleasantly surprised by the fact that every piece of knowledge I feared has turned out not to cause an internal catastrophe once I obtained it.

What did you fear?

Maybe I'm reading too much into this phrasing, but I really don't like that "once I obtained it." It would be plausible if you were saying that you feared things from afar, but once you were forced to deal with them, it turned out that you could live with them, and you could have figured that out if you'd confronted them ahead of time. But it sounds like you're saying that they only turned out to be unproblematic when you got close to them, which sounds suspicious to me.
