" It was right then that I started thinking about Thomas
Jefferson on the Declaration of Independence and the part about our
right to life, liberty, and the pursuit of happiness. And I
remember thinking how did he know to put the pursuit part in there?
That maybe happiness is something that we can only pursue and maybe
we can actually never have it. No matter what. How did he know
that? "
Christopher Gardner, The
Pursuit of Happyness (2006)
