I've never heard of the technique before, but hearing it for the first time in a detailed way as this has taught me a lot of lessons.

Here is one of my struggle

Each time I have a project to accomplish and I have no financial power to carry it out as at that time, without asking me, you will know from my behavior and reaction that I'm struggling with something, I don't know how to hide it. I've been struggling to use the denying technique to overcome this habit, but I keep reminding myself of the reality each time I tried. But I think the answer lies in the Metacognition.

Thanks as always.
