Five years from now I think the concept I will remember the most is the Big 5 personality characteristics. These 5 traits I think can describe everyone so well that it is important to know what type everyone is. When you know what type of personality a person is it is much easier to deal with the person. Whether you are going to sell them a car, serve them food, or treat someone for some sort of illness they may have a lot less conflict will arise and an easier sale, job, or diagnosis it will be. Not to mention how much happier your client will be when you cater for their personality. Therefore, becoming a pro at the Big 5 will help me the most in my career path, no matter which one I pick.
