Watching a talk called Studies on Anger, Resentment, and Forgiveness. Very good stuff. In there he mentions a list of symptoms of pride. They are from a book by William Backus called What Your Counselor Never Told You.
Like he says, if you have these symptoms, especially if you have several of them, you should watch out. You may have pride, and soon you might also find yourself with a wounded pride, which will bring emotional health issues into your life; resentment, hostility, anger, et cetera.
