“including so things” is confusing to me. Is it correct grammar or did you make a mistake?
If I rewrote the sentence like this (below) will it have the same meaning.
This = Knowing how to handle open questions or candidate ideas that one doesn’t yet have a conclusion about is an important skill. That includes knowing how to be open to an idea without it leading to negative emotions.
Edit: The second paragraph is actually a question. I put a full stop there instead of a question mark. It’s a mistake that I make quite often.
