One thing we have to know in this life is all fingers are not equal and we don't have to compare ourselves with others because we do not know everything they do or how they started.

Our friends colleagues or family members achieving more than we have actually achieved or as you put it the gap is too much that we cannot meet up to the standard they are living with.

I will say is not something we have to punish ourselves over or get better because of that but I think we have to face it and know how to manage our life's.

The solution to this is for everyone to learn how to be contented with what he or she have being angry won't lead us anywhere or make us achieve more than others, but is the parts which we have to swallow our pride and accept what we have and also know when to reach out to ask for help.
