And a child is born on his brother's heels,
Come sunday morn the first-born is dead,
In a shoebox tied with a ribbon of red.”

“There's a fine line between audacity and idiocy.”

“There is a fine line between insanity and genius.”

“There's a fine line between criminality and genius."

“There's a fine line between a superpower and a chronic medical condition.”

“In this world, there is a fine line between enlightenment and brain damage.”

“The line between failure and success is so fine… that we are often on the line and do not know it.”
