Comparisons with someone is nothing but insulting your own personality. Why you compare with anyone else if everyone are born as a unique identity.
If you are successful then enjoy your life, instead of looking for others failure. If you are failure then try to be introspect about your processes, instead of looking for successful people and upset.
In both the above situations if you are not enjoying or learning yourself then you are just wasting your time.
Comparison is a natural human nature, the people who always compare their own life with others they are never become a happy life.
If you really wanted to grow then start comparing with yourself, compare your yesterday with today, compare with your past skills, knowledge, attitude, finance, relationships with today and make a Greater future.
Don't letting down to your creator by comparing with others.
