I dislike people who are unjustly successful.
Why don't you think that they deserve their achievements?
Because they don't deserve their achievements
It's okay to dislike someone who has found success unjustly, just don't let it eat you up too much. It would be much better to use that energy towards something you want in life. Plus, there's nothing you can do about those situations if they don't involve you.
Ironically, I think it's great when I am unjustly successful.
I am glad that you know your weaknesses and are willing to work on them. Knowing that you can be a hypocrite is and important part of bettering yourself.
