I think it is fair to say that everyone compares against other people at some point. It can be a source of inspiration but it can also be detrimental. Often, people compare the worst in themselves against the best in others. This is natural as many people tend not to show their inside thoughts to others. Thus, it creates a situation where the comparison may not be fair and unnecessarily depressing to the individual . When you think you are worse than someone else, that very same person might think you are better off than him/her.
