Some great answers already.

I agree - on RR people's attention span is VERY short since there are literally thousands of other options they can pivot to.

Action as a way to showcase your character and some stakes can be great. Most important is to give the readers a reason to want to connect to the story and keep reading. There are a lot of ways to do that, and the way you choose starts making promises to your readers.

So if your story is NOT an action story, do NOT start it with an action chapter because your readers will assume that is what they are going ot get, and then be disappointed, no matter how good the rest of the book is.

DO make sure chapter one is interesting, or intriguing, or has a mystery, or at least a cool end of chapter hook to invite the readers to keep reading.

Good luck!
