A poison emotion that eats away at a person's peace of mind, mental well-being, and ability to treat others well.
Resentment is a lack of acceptance and a lack of forgiveness.

These are all other people's actions, reflections of other people's personalities or abilities, yet we allow them to cause us to become resentful. When I first heard those words, I took immediate exception. I don't believe this world is an uncaring place. But he follows them up by saying that the world is impartial, and I have to agree with that.
