I see this more of the quality where you can dive into something you don’t already know how to do with confidence that you can come out the other side.

A lot of people are just really scared of what they don’t know, and don’t even give themselves a chance to self-teach or expand their skills

There’s a fine line, but I don’t think that is what GP is talking about. Chasing the new shiny unnecessarily vs learning a new tool when required/necessary. Plenty of people do the former, and plenty of people also resist the latter (vehemently so, in many cases).
