A few years ago, I read The Inner Citadel: The Meditations of Marcus Aurelius by the late french philosopher Pierre Hadot. In it he makes the case that Meditations were written as type of spiritual exercise (it was never even meant to be published, and I think that the correct translation of the title is To Myself, or something along those lines), where Aurelius would write to himself using vivid language, metaphors, etc., that would also work on his emotional center. He was using the template of Stoic philosophy, but he adopted it in a way that worked for him.
Bringing it into context of the discussion about Helmstetter's work, and as others have mentioned already, it would mean that it's not enough to just repeat stock phrases to yourself, you'd have to talk/write these in such a way that they make sense to you personally, that they carry meaning and that there's an emotional component to it. Or as Gurdjieff would put it, to work with your whole being. This will be different for each person, and adopting some examples of self-talk that Helmstetter gives to be more in line with the C's/forum seems to be the best way to go, as that is most likely to work for us.
Hadot writes (and I'm not sure if it's from the same book mentioned above):

Hadot writes (and I'm not sure if it's from the same book mentioned above):
What's interesting about the idea of spiritual exercises is precisely that it is not a matter of a purely rational consideration, but the putting in action of all kinds of means, intended to act upon one's self. Imagination and affectivity play a capital role here: we must represent to ourselves in vivid colors the dangers of such-and-such a passion, and use striking formulations of ideas in order to exhort ourselves. We must also create habits, and fortify ourselves by preparing ourselves against hardships in advance. In Epicurean communities, people help one another, admit their weaknesses to each other, and warn others of such-and such a dangerous tendency which is beginning to manifest itself in them.
