Emotions are inherent in your nature, but their content is dictated by your mind. Your emotional capacity is an empty motor, and your values are the fuel with which your mind fills it.
Ayn RandAbout Mike the construction worker, friend of Roark: "He worshipped expertness of any kind. He loved his work passionately and had no tolerance for anything save for other single-track devotions. He was a master in his own filed and felt no sympathy except for mastery. His view of the world was simple: there were the able and there were the incompetent; he was not concerned with the latter."
