I've tried a few of Paraliminals in the past. They work, but you have take the action to reinforce the affirmations in it. Otherwise, it's just listening to something, and not doing anything about it.
Instead of asking, "Does it work?" Well, ask yourself, "What can I do to make it work?" or you can even use Afformation (look up Noah St. John) "Why does it work?"
Regarding " I have resistance to plugging other people's stuff into my brain" -- you do that everyday. People's conversation, information from what you read, media, and so on, are all people's stuff coming into your brain as well. However, it's up to you to react to it in a certain way. The more conscious you are, the more choices you'll have.
