Courage isn't inside; it's external. It comes from someone else telling you they believe in you.
Simon SinekWe pursue exercise even though empirically we see no benefit from the energy we're spending and we're hurting. So empirically we should quit. The why is exactly the same thing. You persist even though there are some short-term stresses and even though there is some uncertainty.
