Today I read an article on how to maintain your composure and keep calm while being in an argument. With whatever little experience I have, I have seen people lose their cool more often than not, which actually comes back to bite them in their arse later.
Have a read in free time and see if it helps you. I think no matter where you are in your career or personal life, you can learn a few things from the article. It won’t take more than 5-6 minutes to read the entire piece – LINK.
