Integrity is the hardest thing to prove you have, because the moment you start to tell others of your "good deeds", the ideal becomes moot. Keep doing the right thing, without expectations of getting noticed or praised, or keeping a record of such: then you will have integrity. Be humble, not dishonest, and don't criticize others for not demonstrating integrity. Be happy and focus on what you can do for others and yourself.
Work inspired once again. Doing the right thing can have its rewards, but do not expect them, or get upset if you see another get something for doing the right thing and you do not. Becoming obsessed with being fair in such a situation is damaging to you as a person, because such contempt is only in your heart, not to those you hold it for.
