The alternative: take the red pill, try to see the world as it really is, and resist the cult of positive thinking. We are all flawed, some of us more than the others. That's a reality we ought to accept, hopefully with stoic grace. Positivism [1] above positivity.

You don't need to be delusional about the present to be hopeful about the future.
