Nobody is allowed to be better than me. If I ever start losing at something I basically devote all of my time to getting better at that one thing no matter how unimportant it is just so that I can beat them. But I usually don't end up winning.
Are you a competitive person? If yes, what kind of areas are you most competitive in? Otherwise, are you not fazed by people who are better in what you do, and just accept it?
