It's not just training ourselves, it's companies training us. When people talk about dopamine hits from getting a like on a post, or feeling a buzz from an app, they are explicitly setting out to create a behavioral pattern that benefits them in some way. They are training us like Pavlov's dogs, and while humans are smarter, we do respond to operant conditioning.

At the end of the day, we as people have to react to this environment that's been created, but the people who created it knew what they were doing.
