Success and Failure

Are you a successful or unsuccessful person? Everybody asks  this question many times. In my opinion it depends on your attitude to success and failure. You can succeed when other fail. but at the same time another person can get much more success than you. Who are you  in this case,a successful man or a failure? You succeed when you can see many achievements in your job and conversely you fail, you become a failure when you make mistakes in  your job
