Hope:
"The chronicity of addiction is really a kind of fatalism writ large. If an addict knows in his heart he is going to use someday, why not today? But if a thin reed of hope appears, the possibility that it will not always be so, things change. You live another day and then get up and do it again. Hope is oxygen to someone who is suffocating on despair."
