I like the quote. I did learn this lesson quite late. To try and see what can I be taught even by the nastiest person I could meet. To pull aside the awful appearance and behaviour and take the positive stuff, the little pearl of wisdom. We can learn a lot from everyone, it takes a bit of self awareness. I noticed that once I started to work more on myself, I also began to see the world with different eyes. And every day it is getting better as working on the self is a lifelong process.
