A man who:
- goes everywhere but doesn't belong anywhere.
- knows that life is like caos and only time knows how valuable love is.
- leaves rage, hate and resentment behind, to live life faithfull to his principles: empathy, honesty, willing.
- in every occasion, has given the best that he has in order to make the world a better place.
