Quite a display of pride and prejudice. Someone who says he is modest is not. Someone who judges others as rude and envious carries the same qualities. If you yourself are not or have never been envious or rude to anyone, there would be no need to give yourself the label of nobility, you would simply be humble and kind without emphasising it. If you only wanted to prove yourself to yourself, there would be no need for pictures showing you with sash and award, your graduation from university would be a normal part of your life miles.
True modesty does not promote itself.

Unless you are enlightened or a holy person, you will be as rude, as envious and as underestimating peoples potentials as you perceive it with others, no? You would not answer that you never fail, neither in judgement nor in tasks?
