He’s brilliant. His type grid is very informative. The information about interaction styles really solidified my understanding of the basics. As a result of watching his videos on YouTube, I’ve identified my type and those of my family, which allows me to adjust what I do and say to build my individual relationships with them. I can also type other people pretty easily, which is also very helpful. If I know a person’s type, I can tailor how I say things in a way that best communicates to him or her.
