I hold the opinion that one should be curious about everything but some things only superficially. If you dig deep into something, it changes the experience of it. There's something to be said about being intimately familiar with a subject.

Forcing yourself to be curious about every single thing that crosses your path is a good way to make yourself uncomfortable. I consider discomfort of that kind to be good practice when it comes to confronting the possibility I may be wrong about something.

I guess I have trouble living up to that ideal, but at the same time I have learned to be uncomfortable with being too comfortable. I worry that too much anti-curiosity would lead to too much comfort.
