I’ve been thinking about this for a bit, because affirmations undeniably have real effects. But aspies recoil from the idea because purposeful self-deception is out of the question, regardless of whether it’s effective or a force for good or evil. So I think the answer is to create self-talk that follows stereotypical aspie speech patterns. In addition to meeting the Framing requirements for an ordinary affirmation, aspie self-talk must also be literal, pedantic, factual, and related to idiosyncratic fascinations.
Here’s an example affirmation that’s done well for me: “I will become organized, disciplined, and extremely productive if I will merely apply myself to it.” This is literally true, pedantic, etc., and I have no concern that this will plant false ideas in my head. The only problem I still run into is forgetting to do them (mindfulness is a recurring problem in my life), so I’m thinking about doing another one that goes “If I remember to do my affirmations every day after taking a shower it will become a powerful habit with free, compounding returns.”
