Mastering interactions is basically about two things: expressing your ideas respectfully, and listening attentively. During my career I have been in too many meetings where people had no idea about either of them. In one corner, you usually have the rantologist who, no matter what the topic is, will always rant about his pet peeve. In the other corner, you have the sorryologist, who cannot stop apologizing for his existence. Instead of talking about substance, he spends most of the time apologizing for expressing an opinion. Then you have the repeatologist, who must repeat everything four times to feel satisfied. And then there is me, going crazy.
