person A: I am become so angry and bitter. My brother is having it all while i am at a spot without making any progress 
person B: That's really tough. I can imagine how frustrated you are. Just know that going through trials and struggling is always good for your character and you will end up that much better of a person for getting through it. You can't be too concerned with other's lives_comma_ you just have to try not to compare. 
person A: I am trying my best_comma_ but he lives so close to me and i can see all the progress and my mother do the comparison too. Everyone does it 
person B: Oh well that's too bad but their behavior is not right or fair_comma_ and they will deal with the consequences of that themselves. Forgiving them is good for you and for them. Just try your best to let go_comma_ I know it's tough- but people everywhere are way more successful then you and way less successful and you don't compare yourself to them I hope so why focus on one random guy just because he's your brother.
