What made the hockey stop click for you?

Hi y'all! I've been roller skating for a while and I really want to learn the hockey stop, but no matter how many tutorials I've watched I keep not getting it. I end up just kind of swerving instead of stopping.

I understand in theory what I'm supposed to do, but I think there might be some gap between what I think I'm doing and what I'm actually doing in terms of foot placement, weight distribution and riding the correct edge. What made it click for you? What are some things I should be looking for in terms of how it feels or how I hold myself?

Thanks a lot!
