Thank you for the recommendation. Unfortunately, I don't have access to the market of the English-language literature from where I live, and there's not a chance I'll read it in the next few years. Still, the method you describe from the book is something I have discovered on my own, and it has been very helpful indeed. Being mindful about your mind is a good place to be, for it encourages observation and learning of myself like nothing else, and knowing is half a victory. I've given the description of DBT a read on Wikipedia, and it turned out that I've been already practicing or intending to practice many of the points and methods raised. Indeed, it provides a blueprint for healthy attitudes towards oneself and others and for a healthy living, both bodily and mentally. Thank you for linking me to it; I'll see what I can learn from it.
