I think openness to experience is only one part of the equation. There are other parts, e.g., what are your goals? How do you deal with your emotional state if the experience doesn't go your way? And many more. It's quite complex.

There is a treatment called exposure therapy [0] which actually is used to threat anxiety and for one helps with emotional processing.
