With fame you can't trust everybody. You can't depend on them being there for you as a person. They will only be there because of what you've got you as a person. They will only be there because of what you've got and what you can bring to their life. It's not a relationship-it's a leech.
Courage is a special kind of knowledge: the knowledge of how to fear what ought to be feared and how not to fear what ought not to be feared.
