That is what it takes to be the baddest motherfucker ever at what you do.
Know that your dedication will be misunderstood. Some relationships may break down. The savage is not a socialized beast, and an imbalanced lifestyle often appears selfish from the outside.

That's a mythical title, but it became my compass bearing, my North Star. p111
