I don't dwell on what other people have as advantages over me - if I did, then they beat me twice over.
Yes, some people will have the natural advantage of riches, connections, whatever. What is important, however, is not how far they reached, but how far you reached, and how you did it.
Accept the fact, and then move on and do what you can about it. At least alam mo na in your case, ginawa mo yung best na kaya mong gawin. no one can take that away from you.
