I'm the author of the article. I'm struggling with that myself. I don't have any solution tailored to everybody, because I think everybody is different on that. I'm the type of developer speaking loudly when I try to defend my idea, and I improved a lot over the years, but others won't have any difficulties to argue in a calm fashion, and there is a whole spectrum between. The only things which helped me was meditation and trying, again and again, to breath and trying calm done when I see myself too passionate. But again, I think it's really personal. Thanks for your comment on the formatting! I'll try to justify the text see how it goes.
