You can make that effort of thinking the component architecture ahead and that will definitely help. To be honest I was thinking more about props that you'll know will live inside a component but end up on the redux store anyway. I made this mistake with forms on my first react native app by having any field value on the store. I didn't really need to that and the store got bigger and bigger because of that first choice.

Then we also get the opposite advice, above, _don't_ think about your component architecture when defining state! "Define your state shape in terms of your domain data and app state, not your UI component tree."
