With a person like that, make sure to check he's not a polarity responder (i.e. Everything you say, he has an argument for) - if he is, mix in a few suggestions in your pre-talk along the lines of "many people find this too dificult to do, but..." or "you don't think you could..., huh?"
and phrase some of your EFT statements as highly negative "Even though I could never get over this..." or "Even though I'm going to be stuck with this for ever...", etc.

Basically, if his mind argues with whatever it's being told, you want him to lead himshelf to his eventual success by arguing and debating your comments.

Let me know how it goes & Best of luck!
