Oh my goodness I am struggling with this right now.... I pretty much restructured the whole beginning of my book, so it would start with more conflict (which was a good thing), but even within that it seems most advice wants there to be something happening immediately in the first few lines. I think I naturally prefer a few pages of slow burn, so attacking it from different angles to have immediate action has been interesting but somewhat frustrating.
I have struggled with this, too, because hey I like books that take their time to unfold, so what’s the deal with this demanding that something happen in the first 200 words? But i’m coming to understand it better, or at least a little differently. I’m not sure there has to be immediate action. What there has to be is immediate interest. You can have a car crash on the first page - action - but if readers don’t know who is in the car, they aren’t likely to be terribly interested. You can set up your slow burn, but it has to be interesting enough for readers to come along with you, and ideally you start that interest with the very first sentence and hold it right through until you are ready for the inciting event to occur. You need to create reader curiosity from the very start, whether you do it with your inciting event or with something else.
It also might help to read the notion of “action” a little broadly - not just car chases or fist fights, but rather something happening - anything at all that happens in front of the reader and creates tension, such as a tense conversation, or a character tearing apart her apartment looking for her lost keys. Anything other than passive description and scene-setting. When I think of creating reader interest by putting that kind of action on the first page, it’s helping me reconcile the notion of “action right away” with the slow-burn approach to plot building.
Caveat: There might be different preferences in some genres.
