As someone with an incredibly "addictive personality", I've always seen it much more simply. I become addicted to things when there's nothing else I'd rather be doing that is incompatible with the addictive behavior. Like if I'm sitting on the couch scrolling on my phone, if there was something else I'd rather do (not something that I'd "ought to" rather be doing but don't actually want to) then I would be doing that instead.
