I like Psychology today too. Knowledge is power and understanding the dark traits in some of these people helps to see the red flags sooner rather then later. I also like the use of the
DISC. This is a useful personality tool for use either in the workplace or for relationships. There's another fun test you can do online
16Personalities. My daughter and I were freakishly the same in personality on this test. We still laugh about it today because of one trait we have we do way too often.
