I was really into Myers-Briggs in my early 20s. As a bit of a lost soul it was a great beginning for understanding how I could be different from other people. It’s right up there with “Men are from Mars; Women are from Venus.” (Talk about a book that probably hasn’t stood the test of time!)
I've also used Myers-Briggs quite a lot in my 20s as well.
It helped me a lot to understand why and how some people function differently than others. Instead of thinking "this guy is an asshole", I began to think "I understand this guy does not behave correctly when dealing with this kind of stress" and I could improve the way I communicate with different types of people quite a lot.
