We 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.
Simon SinekA parent does not do everything for their kid. A parent that does everything for their kid produces a kid with no self-confidence. If our parents fixed everything for us and did not allow us to do anything on our own, or intervened every single time, we would all grow up to be completely dependent. The reason we grow up to be healthy adults is because our parents played this game of giving us responsibility, disciplining us when necessary, letting us try, letting us fail.
